| Résumé |
|
The chemistry of phosphates of barium and tetravalent cations [BaMIV(PO4)(2)] is reviewed. Such phosphates crystallise in the C2/m space group for M-IV = Ti, Zr, Hf, Ge, Sn, and Mo, and in the P2(1)/n space group for BaTh(PO4)(2). The existence of BaMIV(PO4)(2) in which M-IV = 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.
