Improvement of Anti-Hydrolytic Property of AlN Powder Modified by the Rare-Earth Salts

Article Preview

Abstract:

In this article, the high-performance modified AlN powder was prepared, using Y(NO3)3·6H2O as the modifying agent, and characterizing by pH meter, TG , XRD and SEM. The results show that the Y2O3 coating was formed on the AlN surface, the pH value of aluminum nitride of treatment suspension solution maintains 7.75 in water bath for 100 hours. Therefore the conclusion is that surface modification with rare earths can effectively inhibit the hydrolysis of the AlN powder.
