Magnetic Dielectric Oxides: Subsolidus Phase Relations in the BaO:Fe2O3:TiO2System

Autor: Robert S. Roth, J. M. Loezos, Terrell A. Vanderah

Publikováno v: Journal of Solid State Chemistry. 121:38-50

The BaO–Fe2O3–TiO2ternary phase diagram has been investigated at 1250–1270°C in air. X-ray diffraction studies of approximately 150 polycrystalline specimens at room temperature confirmed the existence of sixteen ternary compounds. Two of thes

Subsolidus Phase Equilibria and Crystal Chemistry in the System BaO—TiO2—Ta2O5

Autor: Theo Siegrist, Robert S. Roth, Winnie Wong-Ng, Terrell A. Vanderah, J. M. Loezos, W. Febo

Publikováno v: ChemInform. 34

Subsolidus phase relations have been determined for the BaO:TiO2:Ta2O5 system by X-ray diffraction analysis of ~100 specimens prepared in air at temperatures near but below the solidus (1275 °C to 1500 °C). For the BaO:Ta2O5 subsystem, the formatio
