Dixon packing is a small particle high-efficiency packing made of metal wire mesh, with a diameter equal to its height.

The specifications mainly include 2 × 2, 3 × 3, 4 × 4, 5 × 5, 6 × 6, 7 × 7, 8 × 8, 9 × 9, 10 × 10, 11 × 11, 12 × 12, etc.

Due to the capillary action of metal wire mesh, the liquid can be well dispersed and form a film, which is conducive to sufficient mass and heat transfer between gas and liquid, and can significantly eliminate unstable phenomena such as channel flow. The pressure drop of the θ ring packing is related to factors such as gas velocity, liquid spray rate, system density, surface tension, viscosity, and the characteristics of the packing, as well as the amount of pre flooding treatment of the packing.

The hysteresis of dixon packing is greater than that of similar solid fillers, and the surface wetting is also more complete than that of general ceramic rings, resulting in a higher film formation rate and higher separation efficiency. The theoretical plate number of θ ring packing decreases with the increase of packing size and tower diameter, which is more pronounced for packing in small diameter towers.

The increase of tower diameter leads to a significant decrease in the theoretical plate number (when Dr/d>10, HETP=0.8-1.2dr, while when Dr/d>70, the packing efficiency is significantly reduced). It increases with the increase of gas velocity and decreases with the decrease of surface wettability of the packing. θ ring packing is mainly used in laboratory and small batch, high-purity product separation processes. (Compared with single-layer, double-layer has greatly improved mechanical properties and separation efficiency. Generally, double-layer is selected for sizes of 5 × 5 or more.)

The Path to Breakthrough: Resonance Between Technological Iteration and Market Demand

Technological Breakthroughs: Localization and Process Optimization

Powder Preparation: Localized Breakthrough via Carbothermal Reduction
The mainstream methods for producing aluminum nitride (AlN) powder (e.g., direct nitridation) depend on high-purity aluminum and extreme conditions, while Japanese firms like Tokuyama dominate the high thermal conductivity AlN substrates market. Chinese researchers have innovated the AlN carbothermal reduction process, using alumina and carbon black to achieve simultaneous reduction and nitridation at 1,600°C. This slashes AlN powder production costs by 60%, lowering prices from 200–300/kg to under 200–300/kg to under 80/kg. By tuning reaction parameters, submicron AlN powder (0.5–1.5 μm) can be made, meeting strict demands for AlN ceramic applications in 5G and power electronics.

Low-Temperature Sintering: Nano-Modification Cuts Energy Use
Traditional AlN sintering temperature reduction required >1,800°C, consuming 35% of production costs. Shanghai Institute of Ceramics developed a nano-YAG coating for AlN ceramics, enabling low-temperature sintering of AlN at 1,480°C. This reduces energy use by 30% and cuts Y₂O₃ in AlN sintering from 5wt% to 2wt%, avoiding secondary phases that degrade AlN thermal conductivity (>190 W/(m·K)).

Emerging Demand: 5G and Wide-Bandgap Semiconductors Drive Growth

With SiC/GaN devices pushing junction temperatures past 200°C, AlN vs. Al₂O₃ for power electronics is tilting toward AlN. The AlN market growth in semiconductor industry is robust, with substrates for automotive radar and data centers fueling a projected $1.2B market by 2023 (15% CAGR).

Policy Support: China’s Push for AlN Self-Sufficiency

China’s 14th Five-Year Plan prioritizes AlN powder supply chain localization, with subsidies to boost AlN self-sufficiency in China 2025 to >50%.

Conclusion: AlN’s Industrial Tipping Point

While direct nitridation vs. carbothermal AlN debates persist, cost of AlN powder per kg and process maturity remain hurdles. Yet with AlN in high-power LED packaging and 5G expanding, the material is transitioning from lab to fab. For investors and engineers, tracking how to reduce AlN manufacturing cost and AlN substrates for SiC/GaN devices will be key to capitalizing on this shift.

In modern industry,advanced ceramic materials play a significant role due to their unique physical and chemical properties. Among aluminum-based ceramics, aluminum nitride (AlN) and aluminum oxide (Al₂O₃) are two highly regarded materials, yet their market positions are vastly different: Al₂O₃ dominates the mainstream, while AlN has a penetration rate of less than 30%. Why has the superior-performing AlN failed to replace Al₂O₃? This article delves into the scientific logic and industrial realities behind this phenomenon.

1. The "Hardcore" Advantages of Aluminum Nitride

Thermal Conductivity: A Crushing Physical Difference
AlN thermal conductivity (170–200 W/(m·K)) is 7–10 times that of Al₂O₃ (20–30 W/(m·K)).

This gap stems from differences in their crystal structures:

AlN Crystal Structure: Aluminum nitride belongs to the hexagonal crystal system, where aluminum and nitrogen atoms are connected by strong covalent bonds, forming a dense atomic arrangement. This structure not only has high bond energy but also minimal lattice vibration (phonon) resistance, enabling highly efficient heat conduction.

Limitations of Al₂O₃: In the crystal structure of aluminum oxide (α-Al₂O₃, corundum structure), oxygen atoms occupy larger spaces, and the ionic bond characteristics between aluminum and oxygen atoms cause severe lattice vibration scattering, hindering heat transfer.

This property makes aluminum nitride (AlN) ceramic the preferred high thermal conductivity heat dissipation substrate for high-power electronics, 5G base stations, RF devices, LED packaging, and power modules, offering excellent thermal management and electrical insulation for advanced semiconductor applications. For example, AlN heat dissipation substrates can reduce chip junction temperatures by over 30%, significantly extending device lifespan.

Insulation Performance: The "Guardian" in High-Temperature and Extreme Environments

AlN's dielectric constant (8.8) is lower than that of Al₂O₃ (9.8), and its insulation resistance stability is superior under high temperatures (>500°C) or high-humidity conditions. This is due to the strong covalency of its chemical bonds and low oxygen vacancy defect rate. In aerospace, electric vehicle battery modules, and similar scenarios, AlN can prevent safety hazards caused by partial discharges.

Chemical Stability: Dual Protection Against Corrosion and Radiation

AlN exhibits far greater corrosion resistance to molten metals (e.g., aluminum, copper) than Al₂O₃, and its crystal structure is less susceptible to damage in high-radiation environments (e.g., nuclear industry). For instance, after the Fukushima nuclear disaster in Japan, AlN was listed as a key research material for radiation resistance.

2. Penetration Rate Below 30%: The Dual Dilemma of Technology and Market for AlN

Manufacturing Process: Crossing the "Valley of Death" Between Lab and Mass Production
The industrialization of AlN began as a battle against physical limits. Its synthesis process requires temperatures above 1800°C in a nitrogen atmosphere, with aluminum powder purity exceeding 99.99%. Any trace oxygen impurities (over 0.1%) can lead to the formation of AlON impurity phases, acting as "thermal landmines" in the crystal and causing a sudden 30% drop in thermal conductivity.

The sintering stage is even more challenging—conventional pressureless sintering struggles to achieve densification. If hot isostatic pressing (HIP) is employed, equipment costs skyrocket; if sintering aids like Y₂O₃ are added, temperatures can be lowered, but second-phase particles form within the material, obstructing phonon transmission.

In contrast, Al₂O₃ production is a mature industrial symphony. Its raw materials are inexpensive, the process window is broad, and conventional sintering below 1500°C yields dense ceramics, with production costs only 1/3 to 1/2 of AlN production. This "crushing" cost advantage keeps Al₂O₃ far ahead in the industrialization race.

In cost-sensitive sectors like consumer electronics, the disadvantages of Aluminum Nitride for Electronics (AlN) are even more pronounced. For smartphone heat sinks, Al₂O₃ solutions cost just 0.3–0.5 perpiece,while AlN—even if priced down to 0.3–0.5 per piece,while AlN—even if priced down to 2—faces accusations of "over-engineering." This cost-performance gap confines AlN to niche high-end markets.

Its chemical structure gives it good oil resistance, water resistance and chemical resistance, and it is also compatible with a variety of plastics and additives. These characteristics make CAB resin have a wide range of application prospects in the plastics industry.

2. Application of Cellulose Acetate Butyrate in Plastic Products

2.1 Transparent Plastic Products

CAB resin has extremely high transparency, almost comparable to glass. Therefore, it is often used to manufacture plastic products that require high transparency, such as eyeglass frames, optical lenses, transparent packaging boxes, etc. These products are not only beautiful in appearance, but also effectively protect the internal items from the influence of the external environment.

2.2 Weather-resistant plastic products

Due to its excellent weather resistance, CAB resin is often used in the manufacture of outdoor plastic products. For example, outdoor furniture, auto parts, building decoration materials, etc. These products can still maintain good performance and appearance in the environment of long-term exposure to sunlight, rain and wind and sand.

2.3 Chemical-resistant plastic products

The chemical resistance of CAB resin makes it perform well in the manufacture of plastic products that need to contact chemicals. For example, laboratory utensils, chemical containers, pipes and valves, etc. These products will not corrode or deform due to contact with chemicals during use, ensuring the safety and reliability of use.

2.4 Plasticity plastic products

3.2 Processing performance

CAB resin has excellent processing performance and can be processed at a lower temperature to save energy. At the same time, it has good fluidity and is easy to mold, and can produce high-quality plastic products.

3.3 Versatility

CAB resin can not only be used alone, but also blended with other plastic materials to improve its performance. For example, blending with polycarbonate (PC) can improve its impact resistance, and blending with polypropylene (PP) can improve its heat resistance.

In general, Cellulose Acetate Butyrate has a very good performance in the plastics industry.

🔬 At a molar fraction of 5% vinyl acetate, the mechanical properties of EVA (ethylene vinyl acetate copolymers) become very similar to those of soft PVC.EVA is flexible in its own right, which gives it a number of advantages, such as the disadvantage of avoiding the migration of plasticizers, which is the main reason for the gradual replacement of PVC.

💪 These copolymers have a higher modulus and better processing properties than typical elastomers and do not require vulcanization considerations. Polyvinyl alcohol can be obtained by hydrolysis of polyvinyl acetate. Poly(vinyl alcohol) is an atactic cubic polymer but does not disrupt the lattice structure due to the small hydroxyl groups. Therefore, ester bases that are not sufficiently hydrolyzed reduce crystallinity and the number of intermolecular hydrogen bonds.

💧 Highly hydrolyzed poly(vinyl acetate) (containing fewer unhydrolyzed ester groups) has a higher crystallinity. As the degree of hydrolysis increases, the molecules become easily crystallized. If these molecules are not sufficiently dispersed before dissolution, hydrogen bonding will cause them to associate with each other. In order to achieve hydrolysis levels above 98%, manufacturers need to operate at a low temperature of 96°C to ensure that the larger molecules have sufficient thermal energy to dissolve.
