ABSTRACT:
A method is disclosed for increasing the ceramic yield of a ceramic material obtained by firing a R.sub.3 SiNH-containing silazane polymer to an elevated temperature in an inert atmosphere or in a vacuum. The method involves adding certain boron compounds to the R.sub.3 SiNH-containing silazane polymer prior to firing. Suitable boron compounds include, among others, metaboric acid, orthoboric acid, and organoboron compounds of the general formula BR.sub.3 " where R" is selected from the group consisting of alkyl radicals containing 1 to 5 carbon atoms, phenyl radicals, and --OR'" radicals where R'" is an alkyl radical containing 1 to 4 carbon atoms.
