TITANIUM ALUMINIDES SYNTHESIS BY ALUMINO-CALCIOTHERMIC REDUCTION OF TiO۲

Abstract: Production of titanium aluminides in TiO۲-Al-Ca system has been investigated. For this purpose, different compositions of raw materials were studied in a special reaction vessel. In a special case, the non-completed reaction of TiO۲ with Al and Ca resulted in the production of granulates of titanium aluminides especially Ti۳Al and other Ti – Al phases as the metallic product and Ca۱۲Al۱۴O۳۳ as the non-metallic product. Remelting of metallic granulates led to production of TiAl ingot.
