Paper Title:
Synthesis and Characterisation of BaMIV(PO4)2 in the View of Conditioning of the Actinides
  Abstract

We present here a systematic study on the BaMIV(PO4)2 double phosphates. We successfully synthesized the compounds with MIV = Ti, Zr, Hf, Ge, Sn and Th. Several attempts to obtain the compounds with MIV = Pb, Re, Ce, U and Np have been also performed and the preliminary findings are discussed here. In agreement with previous studies, the BaMIV(PO4)2 (MIV = Ti, Zr, Hf, Ge and Sn) compounds crystallize in the C1 2/m 1 space group (yavapaiite structure), while BaTh(PO4)2 exhibit a different structure. The results on the stability of the BaZr(PO4)2 and BaHf(PO4)2 yavapaiite-like compounds upon heating and cooling are presented.
