Improvement in varistor properties of CaCu3Ti4O12 ceramics by chromium addition
Elsevier (2019-11-17)The effect of chromium addition on the structure and electrical properties of CaCu3Ti4O12 is studied. Compositions based on the formula CaCu3Ti4-xCrxO12-δ (x = 0, 0.025, 0.050 and 0.075 mol%) are prepared by solid-state ... -
Spinel–rock salt transformation in LiCoMnO4−δ
The Royal Society (2016)The transformation on heating LiCoMnO4, with a spinel structure, to LiCoMnO3, with a cationdisordered rock salt structure, accompanied by loss of 25% of the oxygen, has been followed using a combination of diffraction, ... -
Structural and optical properties of CaTiO3 perovskite-based materials obtained by microwave-assisted hydrothermal synthesis: An experimental and theoretical insight
Elsevier (2009)CaTiO3 powders were synthesized using both a polymeric precursor method (CTref) and a microwave-assisted hydrothermal (CTHTMW) method in order to compare the chemical and physical properties of the perovskite-based material ...
