Abstract: PURPOSE: An alpha case interfacial reaction controlling mold for casting titanium alloy and a method for manufacturing the same are provided to effectively control an alpha case which is an interfacial reactant generated in a titanium alloy casting process. CONSTITUTION: A mold for casting titanium alloy includes ZrO_2, Ti_xZr, Ti_xCa, and TiO_2 which are obtained by mixing and sintering CaO stabilized ZrO_2 powder and titanium powder. The 0.3 to 50 weight% of CaO stabilized ZrO_2 powder and 0.3 to 50 weight% of titanium powder are mixed. The mixed powder is formed into a slurry shape in order to form a mold in a desired shape. The slurry shaped mixed powder is formed into the mold.
