PCT No. PCT/US93/00978 Sec. 371 Date Dec. 8, 1994 Sec. 102(e) Date Dec. 8, 1994 PCT Filed Jan. 28, 1993 PCT Pub. No. WO93/25496 PCT Pub. Date Dec. 23, 1993.A method for making a moisture-resistant aluminum nitride-containing powder which includes (a) coatng a layer of silicate onto aluminum nitride-containing powder having aluminum nitride on at least a portion of its surface and (b) heat-treating the coated aluminum nitride-containing powder at a temperature of from 350 DEG to 1000 DEG C. for a period of time sufficient to cause the silicate to react with the surface aluminum nitride thereby forming a layer of Si-Al-O-N bonded to the surface aluminum nitride. The silicate has alkyl or alkoxyalkyl radicals attached thereto. The method yields a moisture-resistant aluminum nitride-containing powder having a layer of Si-Al-O-N reaction-bonded to the surface aluminum nitride.
