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 ...
Mechanochemical synthesis of PbTiO3 from PbO and TiO2
(Journal of Alloys and Compounds, 1998)
Data on mechanochemical synthesis of PbTiO3 from PbO and TiO2 without subsequent heating of activated mixtures are presented. Physical and chemical processes occurring during mechanical activation are followed by the X-ray ...
