| description | The invention relates to alkali metal silicate binder compositions, particularly for use in the production of foundry moulds and cores. The binders of the invention are in aqueous solution and are obtained by mixing: (i) an alkali metal silicate, (ii) a substantially water soluble carbohydrate selected from glycans; glycan oligosaccharides; glycanitols; glycanitol derivatives of oligosaccharides; and monosaccharides and disaccharides and derivatives thereof, and (iii) an oxyanion of boron, tin, germanium, tellurium or arsenic, which can form with the carbohydrate a water soluble complex. The binders of the invention give better breakdown properties and improved surface finish of metal castings produced using moulds and cores formed using the binders. |
