The redox behaviour of chromium oxide in CrO x /La 2 O 3 , CrO x /La 2 O 3 /ZrO 2 and CrO x /ZrO 2 mixed oxide systems has been investigated by temperature-programmed reduction (TPR), photoelectron spectroscopy (XPS) and Raman spectroscopy (RS). The

The structure of glasses in the Li2O–B2O3–V2O5and ZnO–B2O3–V2O5systems of a high modifier content ([Li2O, ZnO]/[B2O3] ratio > 1) and 10 to 50 mol % V2O5are investigated by V-KEXAFS and Raman spectroscopy. In the glasses investigated, VO4tetra

The tribological behavior of self-mated ceramic composites, like SiC-TiC, Si3N4-TiN and (Ti, Mo) (C, N)+Ni, were characterized under dry-sliding friction. The coefficient of friction still remains unchanged on a level known from SiC and Si3N4 ceramic

The Raman spectra of amorphous phases are sometimes difficult to interpret because the information content of spectra is usually low. However, laser-induced damage can be used in order to transform materials into phases that provide spectra that can
