摘要： PURPOSE:To obtain a mold material for casting a Ti material which does not oxidize or deteriorate the Ti material in the mold material consisting essentially of silica and contg. a hardener composed of phosphate and basic metallic oxide by adding alumina to silica. CONSTITUTION:The mold material for casting pure Ti or Ti alloy consist of the main material consisting essentially of silica and alumina and the hardener composed of the phosphate and basic metallic oxide. The mold material is obtd. by kneading about 10-82wt% silica, about 10-82% alumina, about 5-15% phosphate and about 5-30% basic metallic oxide with the colloidal silica and calcining the mixture at >=about 1,000 deg.C after curing. Said material is produced by forming the refractory structure of >=1 kinds among mullite, spinel and cordierite in the mold material. The mold material permits casting of the pure Ti and Ti alloy having a high m.p. of 1,600-1,700 deg.C and permits the casting of the molten metal at an ordinary temp.
