  • Method of producing dense sintered silicon carbide body from polycarbosilane
    Patent number: 4374793
    Abstract: A method of producing a dense sintered silicon carbide body, which is high in flexural strength, purity and strength at an elevated temperature, from polycarbosilanes is disclosed. This method comprises the following steps of:A. polymerizing organosilicon compounds to obtain insoluble and unmeltable polycarbosilane of which the melting or softening temperature lies higher than its thermal decomposition temperature;B. grinding this insoluble and unmeltable polycarbosilane to powder;C. decomposing this powder thermally in the range of 600.degree. to 2200.degree. C. in a nonoxidizing atmosphere to obtain silicon carbide;D. molding this silicon carbide powder; andE. sintering the thus molded body in a nonoxidizing atmosphere.
