Silicon Carbide Refractories (CUMIFRAC A24) are produced from silicon carbide, a raw material synthesized in a resistance-type electric furnace at temperature exceeding 2500°C, through the reaction of silica with carbon. They have a thermal conductivity 10 times that of fireclay refractories, good corrosion and thermal shock resistance, and can be formed into complex shapes.

The crushing and grinding processes also contaminate the silicon with iron due to wear of the crushing and grinding equipment. During crushing and grinding of blocks of silicon the fracture surfaces of the silicon particles will oxidize and the produced powder will thus have an unwanted oxide layer on the surface of each individual particle.

The earliest method of silicon purification, first described in 1919 and used on a limited basis to make radar components during World War II, involved crushing metallurgical grade silicon and then partially dissolving the silicon powder in an acid. When crushed, the silicon cracked so that the weaker impurity-rich regions were on the outside .
