Abstract
The present invention is directed to a reaction product of silica sand and of particulate carbonaceous material to form, silicon carbide on the surface of the carbonaceous particles and within the pores thereof, with the silicon carbide ultra-microcrystallites having a diameter of approximately 500 Angstroms and the composition comprising approximately 60% silicon carbide. The present invention is further directed to the process by which the ultra-microcrystallite silicon carbide product is made. In other preferred embodiments the ultra-microcrystallites of silicon carbide may be separated from the carbonaceous material by heat or physical methods to form a substantially pure ultra-microcrystallite silicon carbide product.
