摘要：Preceramic compositions which are useful in providing protective ceramiccoatings on silica foams, carbon/carbon composites, graphite, and other materials areprepared by dispersing about 0-3 parts by weight of aluminum-silicon eutectic, about 0-4parts by weight of silicon carbide, about 1.5-5 parts by weight of silicon boride, and about0.4-5 parts by weight of silicon metal in a solution of one part by weight of a polysilazanein an organic solvent.
