Ultrafine powders of ceramic materials have been prepared by the decomposition of organometallic complexes, 1,2 thermal decomposition, 3,4 vapor deposition or pyrolysis of inorganic polymers. 5 Processes beginning with preparation of the necessary organometallic complexes from commercially available inorganic salts (using hydrolytic methods which have been fully developed) have already been shown to have numerous advantages over other techniques in the preparation of highly pure and homogenous ceramic powders. 6,7 Thus, we have synthesized our ceramic metal oxides, 8, 9, 10 as well as our nitrides 11,12 and carbides 13 by methods along these lines. In this article we will summarize some of the general characteristics of these processes for the preparation of ultrafine (<100A) and ultra- pure (99.99%) ceramic oxides, nitrides, and carbides, among which are A1203, Y203, zyttrite, Al203-Zr02 eutectic, mullite, various spinels, AIN, amorphous Si3N4, α-Si3N4 ß’-sialon, and ß’-SiC. We will also report on the sinterability of these materials at or below 1500°C.
