Abstract
PURPOSE:To produce ceramic shell molds of high strength easily by using the mud-like slurry prepd. by dispersing inorg. fibers together with fine powdery refractories into hydrolyzed liquid of colloidal silica or ethyl silicate. CONSTITUTION:In the stage of producing ceramic shell molds to be used in a precision casting method, the mud-like slurry prepd. by dispersing and suspending fine powder of refractories such as zirconium, fused silica, chamotte, Alundum, silicon carbide or the like in hydrolyzed liquid of collidal silica or ethyl silicate and further mixing inorg. fibers such as glass fibers, carbon fibers or the like of 1-15mm. lengths therewith at 0.1-1.0% basing on the weight of the fine powdery refractories is used as the material. The ceramic shell molds of high air permeability and strength are obtained with less coating layers to be applied on wax patterns.
