ABSTRACT:
A method for making a component for a semi-conductor diffusion furnace by blending two types of silicon carbide powders, that is, 10 parts by weight of intermediate silicon carbide having an average particle size of 10-30 microns and 10-25 parts by weight of coarse silicon carbide having an average particle size of 80-200 microns, thereby to make a mixture, admixing an organic binder with the mixture, thereafter granulating the mixture thereby to produce pellets, preforming the pellets by a rubber press thereby to produce a formed body, presintering the formed body thereby to produce a presintered body, and impregnating the presintered body with silicon and simultaneously sintering it.
