PROBLEM TO BE SOLVED: To provide a slurry for precision casting mold for active metal having viscosity stability of a slurry for long time, in order to manufacturing the precision casting mold having uniform thickness and strength with which it is important on a process that the viscosity of the slurry used to the manufacture of the precision casting mold has the stability for the long time and is hardly changed. SOLUTION: This slurry for precision casting mold is contained with a zirconia sol, refractory powder and organic-base carboxylate. Since the slurry for precision casting mold is used for long time, and the frequency of the pouring supplement of the new slurry for compensating the deterioration of the slurry can be reduced, the manufacturing efficiency can be improved.
