Abstract
PURPOSE: To produce a compsn. having high strength at high temps. and high density and suitable for use as a heat resistant structural material by adding a silicon component to silicon carbide in excess of the stoichiometric silicon content of the silicon carbide.
CONSTITUTION: Silicon carbide powder of about 10μm or less in average diameter is blended with about 0.5W10wt% of an additive such as boron, beryllium or aluminum and a sol. org. cpd. such as organopolysiloxane in an amt. of 0.5W 10wt% in excess of the stoichiometric silicon content of the silicon carbide. This blend is then preformed under press. at room temp. and hot pressed at about 1900W 2100°C under about 100W700kg/cm2 for about 1W60 min in a nonoxidizing atmosphere to obtain a sintered body the density of which is about 95% or more of the theoretical density of silicon carbide.
