| Abstract: | A new identification and indexing for the phase BaAl2Ti5O14 were accomplished using an X-ray diffraction technique. The new lattice parameters for the tetragonal lattice structure are: a0=9.990 × 10-10 m and c0=12.264 × 10-10 m, with a corresponding volume 1.224 × 10-27 m3. The data provided by the Joint Committee on Powder Diffraction Standards are inconsistent both in lattice parameter values and Miller indices. The X-ray powder diffraction pattern of BaAl2Ti5O14 was indexed using the LSUCR (least-squares unit cell refinement) computer program. |
