PRODUCTION OF POROUS SILICON CARBIDE SINTERED COMPACT

摘要

PROBLEM TO BE SOLVED: To produce a porous silicon carbide sintered compact having high porosity and high strength and capable of easy control of pore diameter. SOLUTION: Silicon carbide whiskers are mixed with 30-50wt.% α-silicon carbide powder of <=30μm, preferably 0.5-10μm average particle diameter and the resultant mixture is compacted and sintered at 1,90O-2,100 deg.C in a nonoxidizing atmosphere.
