Abstract

Non-conducting inorganic materials are fused by a high-frequency magnetic field, in a non-conducting container, after prior treatment to render them conductive in one of the following ways. In some cases the materials may be rendered conductive by preheating by means other than electric heating. Addition of conducting substances which volatilize or burn without residue at high temperatures, such as carbon or metal powder, may also be employed. In a further modification the particles or pieces of non-conducting material are treated so that a skin or coating of conducting material, such as silicon carbide, is formed thereon. The process is applicable to the fusion of oxides such as alumina, magnesia and chromium oxides, and the fusion of carbides, nitrides and borides.ALSO:In processes for fusing non-conducting inorganic materials, applicable to the manufacture of aluminium from bauxite, titanium from rutile, and zirconium from monazite sand, the materials are fused by a high-frequency magnetic field, in a non-conducting container, after prior treatment to render them conductive in one of the following ways. In some cases the materials may be rendered conductive by preheating by means other than electric heating. Addition of conducting substances which volatilize or burn without residue at high temperatures, such as carbon or metal powder, may also be employed.
