[PDF][PDF] Spectroscopic study of spinel ZnCr2O4 obtained from mechanically activated ZnO–Cr2O3 mixtures
ZVM Stanojevic, N Romcevic… - Journal of the European …, 2007 - researchgate.net
A mixture of starting ZnO and Cr2O3 powders in equimolar quantities was mechanically
activated by grinding using a high energy vibro-mill for 0, 40 and 80 min. The spinel
ZnCr2O4 was prepared from activated mixtures by a conventional solid-state reaction at the
temperature of 900◦ C during 240 min. Raman scattering (RS) and Far-infrared (IR)
spectroscopy were applied to study the local structure of zinc chromium oxide spinels. We
report on an analysis of the vibrational spectra of the spinel ZnCr2O4 structure using both …
