摘要：
Methods of DTA, TG, DSC, IR spectroscopy and X-ray phase analysis were: used to study the thermal dehydration and decomposition of Ca2+ and Sr2+ peroxotitanates to the corresponding metatitanates. The stages of the process and the intermediate phases were identified. The information obtained was utilised to determine the optimum temperatures of heating of the initial peroxotitanates to yield metatitanates with a fairly high degree of crystallinity (for CaTiO3 680 degrees C, and for SrTiO3 650 degrees C).
