Crystal structure of Ce-doped CaMnO3 perovskite
(Ceramics International, 2009)
The synthesis and crystal structure of Ce-doped CaMnO3 perovskite has been investigated. Two powders with nominal compositions Ca0.5Ce0.5MnO3 and CaMn0.5Ce0.5O3 were prepared using a modified glycine/nitrate procedure. The ...
Behavior of silicon carbide/cordierite composite material after cyclic thermal shock
(Ceramics International, 2009)
In the present work Mg-exchanged zeolite and silicon carbide were used as starting materials for obtaining cordierite/SiC composite ceramics with weight ratio 30:70. Samples were exposed to the water quench test from 950 ...
Chemical reduction of nanocrystalline CeO2
(Ceramics International, 2009)
The reduction of commercial and mechanochemically processed CeO2 powders was studied. Nanostructured CeO2, with the crystallite size of 21 nm and the lattice distortion of 0.37%, was obtained during 60 min of milling in a ...
