1. Thermodynamic modeling of hydrothermal synthesis of ceramic powders
2. The influence of anions on the products of BaTiO3 under hydrothermal conditions
3. Crystal data for 1: H8BaCl2O12Sn3, MW=1039.1, T=293 K, orthorhombic, Pnma, a=7.836(2), b=18.350(4), c=10.258(2) Å, V=1475.0(5) Å3, Z=4, Dx=4.68 g cm−3, 1575 unique intensity data to 2θ=53° on a 4-circle Siemens RA diffractometer, full-matrix least-squares refinement on F2, R=0.0508, wR2=0.0829 (I>2σI). The powder X-ray diffraction pattern confirms the phase purity, with three most intense peaks; I=100, d=5.14 Å, hkl=(121/002); I=65, d=1.94 Å, hkl=(035/281); I=45, d=3.46 Å, hkl=(051).
