Two ternary phases, designated τ4 and τ5, were revealed in Al–Ti–Pt. The τ4-phase with equiatomic composition (i.e., AlTiPt) was found to have a hexagonal structure with a=4.3908(9) Å and c=5.4823(10) Å (space group P63/mmc), and the τ5-phase, forming in a compositional range between ∼ Al14Ti58Pt28 and Al21Ti63Pt16, has a tetragonal structure (possible space groups P42nm, P-4n2, and P42/mnm). The refined lattice parameters for Al15Ti60Pt25 are a=9.7019(20) Å and c=5.0231 (13) Å.

The ferroelectric ceramic BaTiO3 was synthesized at 1000 °C for 5 h. The structure of the system under study was refined on the basis of X-ray powder diffraction data using the Rietveld method. The system crystallizes in the space group P4mm（99）. The refinement of instrumental and structural parameters led to reliable values for the Rp, Rwp and Rexp.We use the TOPAS software of Bruker AXS to refine this ceramic powders and show its conformation
