摘要

Since it has been recognised that an excess of free carbon is responsible for a decrease in the thermomechanical stability of ceramic fibres,1-3 there is current interest in the preparation of stoichiometric silicon carbide from the pyrolysis of organosili- con polymers.4.s But there exists a paucity of precursors leading to Sic-based ceramics possessing an atomic ratio C : Si == 1 : 1 and most of them exhibit drawbacks6 For example, the polycarbosilane derived from ...
