摘要：

The measurement of soft X-ray spectra, Ti Kα1,2, Lα1,2 and O Kα, of Ti in several titanium oxide compounds was carried out by FE-WD-EPMA (wavelength dispersive – electron probe micro-analyzer with field emission type electron gun) and HRXRF (high-resolution X-ray fluorescence spectroscopy). From the results of measurements, it was found that the valence state of Ti in FeTiO3 (ilmenite) was at least partially TiIII, might be the mixed state of TiIV and TiIII. And, Ti in MgTiO3 (ilmenite system) was confirmed as TiIV. From the discussion, it can be presumed that the effective charge of the oxygen should be not-uniform and should be different subtlety by the cationic difference, Fe or Mg, even if it had equal crystal structure of the ilmenite system, and that this subtlety difference gave any effects on the valence state of Ti.
