ABSTRACT:
A process for making a casting mold or core utilizes a refractory composition including a slurry of yttria, an acid and an organic solvent. The composition is applied to a mold or pattern, dried, and fired to produce a mold or a layer of a mold or core. The articles produced are relatively unreactive with titanium and titanium alloys during casting.
