ABSTRACT:
A significant improvement of the silicon impregnation depth of a carbon precursor body in the siliconizing thereof to make a silicon carbide body is obtained, as well as an accelerated conversion into silicon carbide if activated carbon is used in whole or in part as the carbon powder component of the precursor body. The molding material is preferably 20 to 60% by weight of binder and 20 to 70% activated carbon. This molding material may also usefully contain 10 to 60% by weight of .alpha.-silicon carbide, which may be previously made by siliconizing carbon powder.
