Ultra-fine SiC powder has been synthesized by the carbothermal reduction of silica by microwave and conventional firing techniques. Analysis of these powders by transmission electron microscopy, Auger electron spectroscopy and X-ray diffraction has shown the formation of Beta-SiC. The crystallite size of Beta-SiC produced by the microwave and conventional firing techniques range from 30-200 nm and 50-450 rim respectively. The product obtained from conventional firing also revealed stacking faults over a number of crystallites.
