SINTERED CERAMIC BODY CONTAINING RESIDUAL CARBON, AND PROCESS FOR PREPARING IT

摘要

A sintered ceramic body containing residual carbon is prepared by adding to a pitch body containing a special petroleum pitch as a fine powder inorganic powder granules, then kneading, pressure molding, and reduction calcinating the thus molded body. If necessary, a liquid tar fraction other than the special pitch can be added. It is higher in mechanical strength and chemical resistance at a high temperature and is very useful as a refractory.
