Microsilica or silica fume is a waste material generated from silicon or silicon-containing alloys producing electric furnaces. One of its usage is as an additive in the concrete production. This investigation describes a process to use microsilica as a feed material to produce fine silicon carbide. A thermal plasma reactor is used to convert this waste material into a value added ceramic. Details of the theoretical considerations, experimental work, and characterization are presented in this work
