Zinc Cadmium Ammine Aqua Monophosphate and Its Thermal Transformations

摘要

Synthesis of amorphous zinc cadmium ammine aqua monophosphates Zn_(3-x)Cd_x(PO4)2n(NH3)·m(H2O)(x=0.6-2.4,n=1.3-3.1,m=2.3-3.4)with variable molar ratio of the cations is described.The sequence of thermal transformations of compoundZn_(1.5)Cd_(1.5)(NH3)_(1.4)(H2O)_(3.2)(PO4)2with equimolar ratio of cations is studied,and schemes of its transformation into the crystalline zinc cacl-mium monophosphate Zn_(1.5)Cd_(1.5)(PO4)2 are suggested.
