Abstract

1,173,460. Moulding moulds. FONDERIES DE LAVAL and J. W. F. HITCHON. 29 Dec., 1967 [20 Nov., 1967], No. 59061/67. Heading B5A. A process for making refractory shell moulds comprises the steps of dipping a pattern alternately into an ethyl silicate refractory slurry and a sodium silicate refractory slurry each of which contains additives for gelling the previous coating. The additive to the sodium silicate slurry is one of ammonia, a water-soluble ammonium salt, piperidine, or monoethanolamine and the additive to the ethyl silicate is an acid and one of an alcohol, an inorganic salt which contains the chloride ion and is soluble in water, acetone or dioxane.
