Abstract
11,754. Vereinigte Chemische Fabriken, Landau, Kreidl, Heller, & Co. June 8, 1911, [Convention date]. [Addition to 10,418/11.] Enamels.-A cloudening-agent for white enamels &c. consists of a silica-containing zirconium compound, free from combined alkali and containing a smaller proportion of silica than is present in zircon, and is made by heating a mixture of zirconium compound containing no silica with silica or compounds thereof in the presence of an alkali or earthy alkali and then removing the combined alkali. In an example given, zirconium oxide and silica are mixed in molecular proportions and, after adding an equal weight of caustic alkali, the whole is heated to a temperature above red heat. The reaction product is freed from soluble silicates by treatment with water and the combined alkali is removed by treatment with a weak acid, and after drying or igniting the residue a voluminous siliceous product remains. The proportions of silica and zirconium oxide may be varied and a larger proportion of alkali is used when the mixture is heated to a temperature below red heat.
