PURPOSE:To obtain the subject sintered compact having a high porosity, function as a heating unit, deodorizing effects and catalyst carrier characteristics by constructing electrically conductive ceramic powder consisting essentially of silicon carbide and metallic silicon powder as a raw material with specific porous bonds. CONSTITUTION:An electrically conductive ceramic sintered compact is obtained by using electrically conductive ceramic powder consisting essentially of silicon carbide and metallic silicon powder as a raw material, bonding electrically conductive ceramic grains to fine silicon nitride grains or fiber produced by nitriding of the metallic silicon in a porous form and constructing the sintered compact. The resultant sintered compact has 20-50vol.% apparent porosity and <=1mu average pore diameter. |
