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.
