Solid Solubility of Apatites in Silicophosphates and Silicosulphates

Abstract

Two distinct phases containing phosphorus, silicon and sulphur occur in cement clinker and rhinania fertilizer.-These are solid solutions based on two structural types: apatite (phosphate apatites and ellestedites) and silicocamotite (silicocarnotite and silicosulphate) structures. Ellestedites, Calo (Si04)
