Abstract
The process includes the steps of combining silica with the spent pot liner in order to convert a majority of the spent pot liner into silicon carbide. Specifically, the silica reacts with carbon in the spent pot liner to form silicon carbide. In order to form the silicon carbide, the materials are heated, such as in an electric resistance heater. The formed silicon carbide is free of contaminants and can be used for many useful purposes.
