Ways to expand the output of new types of products based on titanium-magnesium production
Abstract
On the basis of basic equipment, industrial technologies for obtaining chloride melts of refractory metals (used for refining and as catalysts), alloyed titanium (homogeneous titanium-zirconium sponge), high-quality titanium and zirconium powders have been developed. The process of obtaining titanium carbide by magnesium-thermal reduction of a mixture of titanium and carbon chlorides has been studied. The technology of obtaining composite material in which magnesium and its alloys serve as matrix and refractory titanium compounds (carbide, carbonitride) act as strengthening phase has been tested. It is shown that using valuable components extracted from the spent melt of titanium chlorinators, it is possible to obtain materials with high technological characteristics: crystalline scandium, aluminum-magnesium-scandium ligatures.
