A study on the synthesis and thermal properties of alkali earth group-titanate and zirconate

CaTiO3, SrTiO3, BaTiO3, CaZrO3, SrZrO3 and BaZrO3 were synthesized by solid state reaction and mixing method of partial precititation according to the various reaction times and heating temperatures. These synthetic compounds were identified by X-ray diffractometer (ShimadzuVG-1 Type, Japan) and the production ratios (α) were calculated for the intensity of X-ray diffraction. The thermal properties of synthsized compounds were checked by Differential Thermal Analyzer (Shimadzu DT-2B Type). The change of loss in weight and reaction mechanism were discussed at various transition temperatures. (Author)
