Synthesis of Ba2TiOSi2O7 and Ba2TiOSi1.8Ge0.2O7 ferroelectric ceramics and the structure determination by Rietveld analysis

Polycrystalline samples of pure fresnoite compounds of formula Ba2TiOSi2O7 and germanium (Ge4+) doped Ba2TiOSi1.8Ge0.2O7 were prepared by a standard solid state reaction technique using high purity oxides and carbonates. Pure fresnoite was sintered at 1300 C while the Ge4+-substituted compound was s...
