<p><P>PROBLEM TO BE SOLVED: To provide a triturated liquid for a phosphate based investment material which can be directly fed into a furnace even in a ringless state, generating no cracks, excellent in wettability with a wax pattern, sufficiently strong after being embedded and high air permeability, generating no burrs, being dug out easily and furthermore generating no cracks in a titanium casting. <P>SOLUTION: The triturated liquid for the phosphate based investment material is characterized in that it contains one or more wt.% of an acid compound and/or a basis compound. As an acid compound, an inorganic acid and an organic acid may be cited, while as a basis compound, an inorganic alkali and an organic alkali may be cited. <P>COPYRIGHT: (C)2003,JPO</p> |
