Structural Studies on New Ternary Oxides Ba8Ta4Ti3O24 and Ba10Ta7.04Ti1.2O30

Microwave dielectric properties of BaO–Ta2O5–TiO2 system

“…phase, which was a hexagonal crystal structure with P6 3 /mmc space group. In the crystal structure of Ba 10 Ta 5 In order to clarify the influence of the difference in ionic radii between Ti 4+ and Sn 4+ ions on the crystal structure, the lattice parameters of the solid solutions were determined by the Rietveld method, and the results obtained are shown in Fig. 6 and Table 2 respectively.…”

“…In recent work that focused on the crystal structure analysis of perovskite-like structures, Shpanchenko et al 5 …”

Synthesis and Structural Study of Hexagonal Perovskites in the Ba5Ta4O15–MZrO3(M=Ba, Sr) System

“…The pairs of FSO appear due to the shift of the twin lamella. They should be randomly occupied by Ta, Zr, and cation vacancies, thus decreasing the electrostatic repulsion between B cations, probably in a manner similar to that found in the Ba Ta Ti O oxide (12).…”

Microwave frequency dielectric properties of hexagonal perovskites in the Ba5Ta4O15–BaTiO3 system

“…The lattice parameters of solid solutions are linearly dependent on the x. For comparison literature values 11 for some compositions are also listed in Table 1, revealing good agreement. The typical SEM micrograph of as-prepared BTT ceramics is shown in Fig.…”
