Cerium silicates formation from mechanically activated oxide mixtures
Апстракт
Reactions of cerium silicate formation in mechanically activated oxide powders of CeO2 and SiO2 (quarz) were studied. Three different mixtures were prepared, the compositions of which corresponded to Ce2Si2O7, Ce-4.67(SiO4)(3)O and Ce2SiO5. Oxide mixtures were mechanically activated in vibratory mill up to 120 min. X-ray analysis performed on activated mixtures showed that the CeO2 crystallite size decreased with increasing activation time. However, CeO2 lattice distortions passed through a maximum after 30 min of activation. The results obtained after heating showed that reactions proceeded via formation of intermediate compounds. Evidence of the existence of a liquid phase at 1550degreesC is given. (C) 2004 Kluwer Academic Publishers.
