Abstract

11,753. Sellar, W. C. June 28. Silicofluorides.-Calcium fluoride or fluorspar is fused with about twice its weight of calcium chloride. The mass is cooled, ground, and mixed dry with an excess of silica or a suitable silicate, such as calcium silicate. The whole is then treated with an excess of strong commercial hydrochloric acid, and heated until the reaction is complete. The acid solution is filtered off for re-use, and the residue washed with water to extract the silicofluoride compound, which is afterwards precipitated out and separated as a salt by means of a suitable soluble salt, such as potassium or barium chloride.
