Some observations on mechanical activation of the CeO2-ZrO2-SiO2 system
(Journal of Alloys and Compounds, 1999)
Mechanical activation of CeO2-ZrO2-SiO2 mixtures was performed in a high energetic vibratory mill with WC lining and grinding media. It was shown that in air atmosphere the reduction of Ce4+ into Ce3+ took place at 1400 ...
