Synthesis of a new potassium-substituted lead fluorapatite and its structural characterization.

ABSTRACT: Prismatic crystals of partially potassium substituted lead fluorapatite Pb_5.09Ca_3.78K_1.13(PO₄)₆F_0.87 were grown through a solid-state reaction. The structural study conducted by single-crystal X-ray diffraction revealed that the compound crystallizes in the hexagonal P6₃/m space group, with unit cell parameters a = b = 9.7190(5) Å, c = 7.1700(6) Å and V = 587.37(7) ų(Z = 1), as well as final values amounting to R and wR of 0.0309 and 0.0546, respectively. The structural refinement demonstrated that Pb occupies both the (6h) and (4f) structural sites of hexagonal fluorapatite, K occupies the (6h) site, and Ca is placed o
