Synthesis and Crystal Structure of Some Ba-Apatites
Ba 10 (A V O 4 ) 6 L 2 , where A V = P, V, Mn; L = F, Cl, Br ( Z = 1), were prepared by high-temperature solid-phase synthesis and, of them, three phases were synthesized for the first time. The crystal structure of the synthesized compounds was refined by the Rietveld method within hexagonal space...
