METHOD FOR DENSIFYING POROUS SILICON CARBIDE BASE

摘要

A densified silicon carbide body having excellent mechanical strength. This body is obtained by a method of densifying a porous silicon carbide substrate that includes the steps of impregnating a porous silicon carbide substrate with a curable silicone composition that contains a silicon carbide powder, curing the silicone composition, and thermally decomposing the cured product in a non-oxidizing atmosphere. The porous silicon carbide substrate can be densified and improved easily.
