Aluminum nitride modified powder

The anti-hydrolysis treatment of AlN powder is mainly by means of chemical bonding or physical adsorption to coat AlN particles or form a thin reaction layer to prevent the hydrolysis reaction between aluminum nitride powder and water. The aluminum nitride powder was modified by acid solution, and the acid and hydroxyl group on the surface of the aluminum nitride powder were esterified to form a protective film on the surface of AlN particles. Good hydrophobicity, strong water resistance, can greatly improve the application performance of products.

Ceramic substrate

Aluminum nitride ceramic substrate is a new substrate material. The lattice constant of aluminum nitride crystal is a=0.3110nm, c=0.4890nm, hexagonal crystal system, based on aluminum nitride tetrahedral structural unit covalent bonding compound of brazed zinc ore. With a series of excellent properties such as good thermal conductivity, reliable electrical insulation, low dielectric constant and dielectric loss, non-toxic, and matching with the thermal expansion coefficient of silicon, it is considered to be the ideal material for a new generation of highly integrated semiconductor substrates and electronic packages.
