Overview of Aluminum Nitride AlN powder:
Aluminum nitride powder has excellent thermal conductivity, high electrical insulation, and thermal expansion characteristics, making it the best material for sintered bodies.
Aluminum nitride is stable at high temperatures in an inert atmosphere and melts at about 2200°C. In a vacuum, AlN decomposes at ~1800°C. In the air, surface oxidation will occur above 700°C. Even at room temperature, a surface oxide layer with a 5-10 nm thickness has been detected. The oxide layer can protect the material at temperatures up to 1370°C. Above this temperature, bulk oxidation occurs. Aluminum nitride is stable in hydrogen and carbon dioxide atmospheres up to 980°C.

Application of Aluminum Nitride AlN powder:
AlN aluminum nitride is an inorganic, non-metallic material of diamond-like nitride with good thermal conductivity and a low coefficient of thermal expansion. It is a good thermal shock material. With strong resistance to molten metal corrosion, it is an ideal crucible material for melting and casting pure iron, aluminum, or aluminum alloy. Aluminum nitride is also an electrical insulator with good dielectric properties, and it also has good application prospects in electrical component manufacturing.
Electronic packaging materials:
Because aluminum nitride powder has high thermal conductivity and low dielectric constant, it is widely used in electronic packaging. In electronic packaging, aluminum nitride can be used as a thermally conductive material to improve the heat dissipation performance of the device. In addition, Aluminum Nitride can be used as an insulating and dielectric material to manufacture integrated circuits, power devices, and microelectronic devices.
Optical Coating:
Since aluminum nitride has high transmittance and high refractive index, it can be used as an optical coating material. Coating aluminum nitride on the surface of optical components can increase the transmittance and refractive index, thus improving the performance of the optical system.
Wear-resistant coating:
Aluminum nitride coatings have certain wear-resistant properties. They can be applied to various sliding and friction components, such as engine and turbine blades, to improve their anti-wear performance and life.
Biomedical Applications:
Although aluminum nitride is not as widely used as titanium nitride in the biomedical field, it still has some application prospects. For example, in dentistry, aluminum nitride can be used to make dental implants, and so on.
High-temperature structural materials:
Due to the high thermal conductivity and chemical stability of aluminum nitride, it can maintain excellent performance in high-temperature environments. Therefore, in the aerospace and automotive industries, aluminum nitride can be used to make high-temperature structural materials such as high-temperature turbines and combustion chamber components.
Aluminum nitride ceramic is used in various electrical equipment. In addition to the coefficient of thermal expansion and electrical insulation, aluminum nitride ceramics can resist the erosion of most molten metals, such as copper, lithium, and aluminum.
Aluminum nitride substrates have high thermal conductivity and insulation and can be used in power modules (MOSFET, IGBT), LED packages, and modules for cooling and protection circuits.
