Uses of aluminum nitride

(1) Aluminum nitride has high heat transfer capacity, is widely used in microelectronics, has a small thermal expansion coefficient, and is a good thermal shock resistant material.

(2) Aluminum nitride is treated with metal, which can replace bauxite and beryllium oxide for a large number of electronic instruments.

(3) Strong ability to resist the erosion of molten metal, it is an ideal crucible material for melting and casting pure Al, Cu, Ag and Pb alloys.

(4) Aluminum nitride is also an electrical insulator, with good dielectric properties, and it is also promising for use as an electrical component.

Product advantages

Forsman’s aluminum nitride product series are high purity, low oxygen content, products according to different classification: according to the microscopic form of aluminum nitride powder, aluminum nitride powder (spherical), aluminum nitride powder (spherical); According to the application: aluminum nitride powder (waterproof solution). Forsmann products include a large span of particle size distribution, and have achieved industrial production; 10 kg, 25 kg, 100 kg packaging products can be supplied according to customer needs.

Aluminum nitride powder: has high sintering activity and can be used as raw materials for sintered ceramics;

Aluminum nitride powder (spherical): microscopic form of nearly spherical, with high filling capacity, high fluidity, high thermal conductivity, high insulation;

Aluminum nitride powder (waterproof solution): By and with the help of chemical bonds or physical adsorption, a substance is coated on the surface of the AlN particles to ensure its isolation from water, thereby avoiding its hydrolysis reaction.(Because AlN is easy to form aluminum hydroxide with hydroxyl groups in water in a humid environment, and an alumina layer is formed on the surface of AlN powder, the alumina lattice dissolves a large amount of oxygen, reducing its thermal conductivity, and also changing its physical and chemical properties, which brings difficulties to the application of AlN powder.)
