Abstract
Ti K‐edge X‐ray absorption near edge structure (XANES) spectra of various titanates was measured at various temperatures. The composition, structure and temperature dependence of XANES spectra was investigated especially on the phase transition. Ti atoms are located in TiO6 octahedral sites for the all samples. Ti K‐edge XANES spectra change largely with different compositions, while the temperature dependence of XANES spectra is small in each compound even if undergoing structural phase transition. For the temperature dependence, the pre‐edge intensity has two types of behavior. One is decreasing as temperatures increase, the other is increasing. The former is for PbTiO3 and BaTiO3 perovskite and the later is for CaTiO3 and SrTiO3 perovskite, Mg2TiO4 spinel and TiO2 rutile.
