PURPOSE:To produce a low viscosity slurry of ceramic powder for casting without deteriorating the characteristics of the ceramic powder even if the water resistance of the powder is low. CONSTITUTION:An org. solvent is used as a dispersive medium for ceramic powder and a polyoxyethylene deriv., polycarboxylic acid and polyethyleneimine each having 2,000-20,000mol.wt. are used as deflocculants and added to the ceramic powder by 0.1-2.0wt.% each to obtain the objective slurry of the ceramic powder for casting. |
