Abstract
High purity, fine Si.sub.3 N.sub.4 powder produced by the vapor phase reaction of SiCl.sub.4 with NH.sub.3 is amorphous. The crystallization rate of the amorphous powder is enhanced by heating the powder while in intimate contact with a titanium containing material, for example, TiN codeposited with the Si.sub.3 N.sub.4 by the simultaneous reaction of TiCl.sub.4 with NH.sub.3.
