Abstract

948,197. Refractory shell moulds. MONSANTO CHEMICALS Ltd. June 26, 1962 [July 20, 1961], No. 26283/61. Heading B5A. A wax pattern for the production of a shell mould is coated with a slurry containing a powdered refractory. After the layer has dried the coated pattern is exposed to steam under pressure in order to melt the wax. Microcrystalline or carnauba wax can be used. The refractory materials aluminosilicates, silicon carbide, oxides such as silica, alumina, magnesia or zirconia and various calcined fireclays can be used, preferably with a silica containing binder.
