Abstract
An improved interface coating for a fibrous material composed of a silicon-containing boron nitride having the general composition BSi.sub.x N.sub.1+1.33x, and containing from 2 wt % to 42 wt % of silicon, with substantially no free silicon present. The coating is formed by CVD using reactant vapors of ammonia and a gaseous source of both boron and silicon which flow into the furnace chamber at a controlled flow ratio to nitride the deposit to form the complex coating.
