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 ...
Formation of celsian from mechanically activated BaCO3-Al2O3-SiO2 mixtures
(Journal of Alloys and Compounds, 1999)
A ternary mixture BaCO3-Al2O3-SiO2 was mechanically activated for different lengths of time. Chemical composition of the mixture corresponded to BaAl2Si2O8-BAS As a function of activation time, reaction course was followed ...
