Abstract:

Crystalline structure of polycrystalline fluorapatite Cas (PO4)3F, was investigated by the powder fitting structural refinement (PSFR) method using the x-ray diffraction technique. Atomic position parameters of the constituent atoms of this material were refined. The crystal lattice was found to belong to the hexagonal class of crystals with lattice parameters: ao=9.3642(3) A; co=6.8811(2) A; g=120o. The Rb factor was 2.57%. The overall temperature factor was computed to be 0.284±0.046. The number of molecules per unit cell Z was equal to 2.0.
