ABSTRACT:
The present invention relates to a mold material for casting pure titanium or a titanium alloy which comprises one or more chief materials selected from among silica-alumina mixtures, mullite and spinel and a hardening agent comprising a phosphate and a basic metal oxide and a process for casting pure titanium or a titanium alloy by the use of said mold material. This mold material forms a refractory structure having a melting point higher than that of pure titanium or a titanium alloy therein to enable pure titanium which is unstable in a molten state to be cast stably.
