Аннотация:The system KLa(SO4)2•H2O – SrSO4•0,5H2O was investigated by X-ray diffraction and differential thermogravimetric analysis. It is established that in this system at room temperature is formed 2 types of single-phase solid solutions: the structure of the rhombic modification SrSO4• 0. 5H2O is present in a concentration interval of 82 to 100 mol% SrSO4• 0. 5H2O, and the structure of the hexagonal modification SrSO4• 0. 5H2O is present in a concentration range 18-75 mol% SrSO4• 0. 5H2O. The formation of a new phase of the proposed SrSO4• 2H2O composition was established.
