Abstract
An ilmenite slag containing mainly calcium and titanium oxides and ca-containing ti ores is treated with carbon at above the melting point of calcium carbide and below the melting point of titanium carbide to prepare titanium carbide particles in a calcium carbide matrix. The carbide mixture is cooled, comminuted, and reacted with water to decompose calcium carbide, liberating particulate titanium carbide and forming acetylene and finely dispersed ca(oh)2. The titanium carbide is concentrated by physical methods. The titanium carbide is chlorinated at a temperature below the melting point of the impurity chlorides, but above the boiling point of ticl4 to prepare a high-purity ticl4.
