What is disclosed is a process for preparing R3'SiNH-containing metallosilazane polymer containing boron, titanium, or phosphorous by contacting and reacting chlorine-containing disilanes and certain reactive metal halides with [R3'Si]2NH where R' is vinyl, hydrogen, or alkyl radical of 1-3 carbon atoms, or phenyl. Preferred reactive metal halides include BBr3, TiCl4, and PCl3. The metallosilazane polymers are useful as chemical intermediates to provide silicon-containing chemical compounds. The metallosilazane polymers are also useful in the formation of ceramic material. The ceramic materials may be formed by heating the metallosilazane polymer at elevated temperatures in an inert atmosphere or in a vacuum.
