Abstract
A readily-soluble, substantially anhydrous silicate composition is produced by heating a mixture of a hydrated alkali metal, particularly sodium, silicate, at least as acidic as the meta-silicate and which in the solid state is fusible, and an inert water-soluble alkali metal salt of another acid at 100-200 DEG C. until the loss of weight of a sample when heated to a temperature near to, but below, the softening point of the dried material is less than 5 per cent, the said salt being used in amount sufficient to maintain a porous mass throughout the reaction period, say, not less than 50 per cent by weight of the alkali metal silicate. The alkali metal salt may be the carbonate or bicarbonate, sulphate, chloride or mono-, di- or triphosphate, or the previously produced dried silicate composition. An acidic alkali metal salt may also be present. Drying may be effected in a rotating drum. A cleansing and disinfecting composition may be produced by mixing the dried silicate composition with calcium hypochlorite or bleaching powder.
