Abstract
A method for manufacturing a porous body comprising zirconium oxide and a metal carbide is described. The method comprises mixing a metallic zirconium powder, a metal oxide, and a carbon powder, shaping the mixture in a desired form, and igniting a part or portion of the shaped mixture in an atmosphere inert to a combustion reaction of the shaped mixture. The combustion reaction is caused to continue by the heat of the reaction, so that the zirconium is converted to zirconium oxide, and the metal oxide is reduced with zirconium and converted to a metal carbide to obtain a porous body. This body may be readily divided into fine pieces. If the above procedure is effected under a molding compression pressure, a composite sintered product comprising zirconium oxide and the metal carbide is obtained.
