METHOD FOR PRODUCING REACTION BONDING SILICON CARBIDE

摘要

PURPOSE: Provided is a method for producing a reaction bonding silicon carbide, which supplies melted silicon effectively regardless of the form, size and thickness of the reaction bonding silicon carbide, prevents the cohesion of the melted silicon, and supplies the melted silicon uniformly. CONSTITUTION: The method comprises the steps of: preparing a silicon supplying specimen composed of a silicon powder and a thermosetting resin selected from the group consisting of a phenol resin, a furfuryl alcohol resin and an epoxy resin as a binding agent; preparing a silicon carbide/carbon filling body; contacting the silicon supplying specimen to one side of the filling body in a reaction bonding furnace; and heat treating at the temperature higher than the melting point of the silicon under vacuum or an inert atmosphere to infiltrate the melted silicon in the silicon supplying specimen into the inside of the filling body.
