Valence-to-core X-ray emission spectra have been measured for a number of chromium compounds such as oxides, carbides, borides, nitrides, phosphides etc. The experimental spectra are in good agreement with the calculated ones. They form the basis for

The thermal behavior of anapaite, Ca2Fe2+(PO4)2·4H2O, has been studied by TG/DTG and DSC techniques, complemented by Fourier-transform IR spectroscopy. The anapaite sample, originating from Bellaver de Cerdena (Spain) was identified as such using X-
