The Chemistry of the Phosphates of Barium and Tetravalent Cations in the 1:1 Stoichiometry
The chemistry of phosphates of barium and tetravalent cations [BaMIV(PO4)2] is reviewed. Such phosphates crystallise in the C2/m space group for MIV 1/4 Ti, Zr, Hf, Ge, Sn, and Mo, and in the P21/n space group for BaTh(PO4)2. The existence of BaMIV(PO4)2 in which MIV 1/4 Pb, Ce, and U is further evaluated. Several aspects, such as phase transitions in the compounds with yavapaiite structure, solid solutions of BaMIV(PO4)2 compounds and practical applications are briefly discussed.
