AlN ceramic injection molding components Properties

What is AlN Ceramic Powder Injection Molding Components:

The aluminum nitride chemical formula is AIN. Aluminum nitride is a covalent bond compound, is an atomic crystal, belongs to diamond-like nitride, hexagonal system, wurtzite type crystal structure, non-toxic, white or off-white. AlN Aluminum nitride can stabilize up to 2200℃. The strength at room temperature is high, and the strength decreases slowly with the temperature increase. It is a good heat-resistant impact material with good thermal conductivity and a small coefficient of thermal expansion. It is an ideal crucible material for melting and casting pure iron, aluminum, or aluminum alloy because of its strong ability to resist molten metal erosion. Aluminum nitride is also an electrical insulator with good dielectric properties and promising as an electrical component. The aluminum nitride coating on the surface of gallium arsenide protects it from ion implantation during annealing.

How is AlN Ceramic Powder Injection Molding Components Produced? 

Preparation of aluminum nitride ceramic powders by direct nitriding of Al powder:

The direct nitriding method of Al powder is the earliest method to prepare AlN powder. In this method, aluminum powder is heated in nitrogen. At high temperatures (800~1200℃), aluminum powder and nitrogen directly react to produce aluminum nitride powder; the reaction formula is 2Al + N2 =2AlN.

This method has the advantages of abundant raw materials, low cost, simple process, and no side reaction. However, the disadvantages of this method are also obvious. At the initial stage of the reaction, the surface of aluminum powder particles will gradually form a nitride film, which makes it difficult for nitrogen to penetrate further and hinders nitrogen reaction, resulting in a low yield. And because the reaction between aluminum and nitrogen is strongly exothermic, the speed is very fast, resulting in the AlN powder self-sintering, forming agglomeration, and making the powder particles coarsen.

The preparation methods of aluminum nitride powder include Al2O3 carbothermal reduction, self-spreading high-temperature synthesis, high-energy ball milling, chemical vapor deposition, sol-gel method, plasma chemical synthesis, in-situ autoreactive synthesis, arc melting, microwave synthesis, sol-thermal synthesis, etc.


Applications of AlN Ceramic Powder Injection Molding Components:

1. Aluminum nitride powder with high purity, small particle size, and high activity. It is the main raw material for manufacturing high thermal conductivity aluminum nitride ceramic substrate.

2. Aluminum nitride ceramic substrate has high thermal conductivity, low expansion coefficient, high strength, high-temperature resistance, chemical corrosion resistance, high resistivity, and small dielectric loss. It is an ideal substrate and packaging material for large-scale integrated circuits.

3. aluminum nitride's hardness is higher than traditional alumina's. It is a new type of wear-resistant ceramic material, but it can only be used for parts with severe wear because of its high cost.

4. By using the heat resistance, melt erosion resistance, and thermal shock resistance of AIN ceramics, GaAs crystal crucible, Al evaporation plate, magnetic fluid power generation device, and high-temperature turbine corrosion resistance parts can be made, and its optical properties can be used as an infrared window. The aluminum nitride film can be made into high-frequency piezoelectric elements and large-scale integrated circuit substrates.

5. Aluminum nitride heat resistance, corrosion of molten metal, stable to acid, but in alkaline solution is easy to be eroded. Exposure to wet air on the new surface of AIN reacts to form an extremely thin oxide film. This characteristic can be used as a crucible and casting mold material for metal, copper, silver, lead, and other metals melting. AIN ceramics have good metallization properties and can replace toxic beryllium oxide ceramics in the electronic industry.


Storage Condition of AlN Ceramic Powder Injection Molding Components:

The damp reunion will affect the AlN ceramic powder injection molding component's dispersion performance and use effects. Therefore, it should be sealed in vacuum packing and stored in a cool and dry room; the AlN ceramic powder injection molding components can not be exposed to air. In addition, it should be avoided under stress.
