Abstract

A coating for a wax model in investment casting comprises a refractory of a silicate of alumina such as dehydrated kaolinite Al2O3 2 SiO2) or refractory clay sillimanite (Al2O3SiO2) and mullite (3 Al2O3 2 SiO2) or an aluminium oxide (Al2O3) in the form of calcined alumina or corundum or sexquioxide of chromium (Cr2O3). The binder is a solution of aluminium chloride (AlCl3) or chromium chloride (CrCl3) anhydrous or hydrated in pure water or in a mixture of water and ethyl alcohol or water and methanol, or pure alcohol. The solution also contains a small quantity of organic binder such as soluble starch, gum-arabic, gelatine or shellac, or a mineral dispersive agent such as kaolin, bentonite &c.
