SILICON CARBIDE COMPOSITE BODY

摘要

PROBLEM TO BE SOLVED: To obtain a silicon carbide composite body having a high heat conductivity of >=200 W/mK. SOLUTION: An aluminum-base metal is infiltrated into a porous silicon carbide compact to obtain the objective silicon carbide composite body having >=50 vol.% silicon carbide content. Silicon carbide particles having >=40μm particle diameter in the composite body account for >=55 wt.% of all silicon carbide particles and silicon carbide particles having <=15μm particle diameter account for <=45 wt.%. The heat conductivity of the composite body at room temperature is >=200 W/mK.
