Introduction to AlN powder Aluminum Nitride
Aluminum nitride
is a covalent bonds compound. The chemical formula for AIN is It is anatomical crystal and belongs to the diamond like nitride hexagonal crystal systems.
Aluminum nitride This synthetic mineral is not found in nature. AlN’s crystal structure is hexagonal wurtzite, which has a low density of 3.26g/cm3. It also has high strength, good heat resistance (Decomposition occurs at 3060), and other advantages.
Physicochemical properties of aluminum Nitride AlN powder
AlN remains stable above 2200. It has a high strength at room temperatures and a slow decrease in strength with temperature increases. AlN has a high thermal conductivity and a low thermal extension coefficient making it a good heat shock material. It is a great crucible material to melt and cast pure iron, aluminum or an alloy of aluminum. Aluminum nitride also has good dielectric properties. It is also a promising electric component. It is protected by ionization during annealing thanks to the aluminum nitride coat on gallium arsenide. Aluminum nitride also acts as a catalyst in the conversion of hexagonal to cubic boron nutride.
It reacts slowly at room temperature with water. It can also be produced from aluminum powder, ammonia, and nitrogen at 800 1000. It can be white or grayish-blue in color. Gray powder can be obtained by using the al2O3–C-N2 reaction synthesis at 16001750. Or, you can use aluminum chloride and ammonia gases in the opposite direction. By vapor deposition, the AlCl3/NH3 system can be used to make the coating.
Let’s sum it up:
1. It has a high thermal conductivity of about 320W/m*K, which is close to SiC and BeO, and more than 5x that of Al2O3
2. Excellent electrical properties (eg, dielectric constant, dielectric loss, body resistivity, dielectric strength);
3. Good mechanical properties. The flexural strength of BeO and Al2O3 ceramics is higher than theirs and can be atmospherically sintered.
4. Good optical transmission properties
5. Non-toxic.
Aluminum Nitride AlN Powder – Applications
AlN’s piezoelectric property makes it an ideal material for surface acoustic wave detections. These detectors will be placed onto silicon wafers.
Aluminum nitride ceramics They have high room temperature, high-temperature strength, and a low coefficient for expansion. This makes them suitable to be used as high heat structural parts of heat exchanger materials.
Due to their corrosion resistance against iron, aluminum and other metals, the aluminum nitride clays can be used for crucibles or casting material for melting Al and Cu, Ag and Pb.
Aluminum nitride ceramics High-tech ceramics are a new breed. The characteristics of aluminum nitride substrate include high thermal conductivity and good thermochemical stability. It can be used as a packaging material, heat dissipation, component, interconnect carrier, and circuit components for large-scale integrated and semiconductor circuits. It can also be used as an additive to increase the thermal conductivity or mechanical properties of polymer material. Aluminum nitride clay can also be used in smelting nonferrous metals, semiconductor gallium arsenide, thermocouple protection tubes and high-temperature insulation parts. Aluminum nitride can be used as an electrical insulator and has good dielectric properties. The gallium arsenide’s aluminum nitride coat protects it against ion implantation during annealing.
