Abstract : Load capacity of bar shaped silicon carbide single crystals varies inversely with the length width ratio and boron concentration. As thickness increases, load capacity increases. The effects of temperature, thickness, length, width, boron concentration, and surface treatment are being thoroughly analyzed using data processing equipment. Furture research will concentrate on chemical polishing with chlorine gas, oxygen, KNO3 + KOH, and borax. Electrolysis in water and molten NaOH will also be studied as possible polishing techniques.
