Method for forming beta-silicon carbide whiskers, singly or in a matrix, using an organotitanium coordination compound catalyst

摘要: Beta-silicon carbide whiskers of superior uniformity can be formed, either singly or in-situ in a matrix, by heating source for silicon with carbon (greater than 0 percent but less equal to about 60 stoichiometric, respect the source) presence titanium-containing catalyst, such as titanocene dichloride. Advantageously, titanium catalyst applied drying solution on and sources. The titanium, sources are then heated together, preferably between 1800° C. 1850° C., resulting product containing high quality beta-silicon whiskers. nitride powder, which substantially converted free-flowing whiskers, alternative, formed into conventional ceramic matrix prior conversion so therein will serve reinforcement matrix.
