Influence of mechanical activation on structural and electrical properties of sintered MgTiO3 ceramics
(Belgrade : International Institute for the Science of Sintering, 2009)
The aim of this work was to analyze the influence of mechanical activation on the MgCO3-TiO2 system. Mixtures of MgCO3-TiO2 were mechanically activated for 15, 30, 60 and 120 minutes in a planetary ball mill and after that ...
Influence of Bi2O3 on microstructure and electrical properties of ZnO-SnO2 ceramics
(Belgrade : International Institute for the Science of Sintering, 2007)
The effects of small amounts (0.5; 1.0 and 1.5 mol. %) of bismuth oxide on the microstructure and electrical properties of ZnO-SnO2 ceramics have been studied. Starting powders of ZnO and SnO2 were mixed in the molar ratio ...
Electrical and transport properties of nickel manganite obtained by Hall effect measurements
(Springer, 2009)
Intrinsic resistivity and carrier transport parameters of sintered nickel manganite samples (NTC thermistor grade) were determined using a Hall effect measurement system based on the van der Pauw method. Powder mixtures ...
Microstructural evolution and electric properties of mechanically activated BaTiO3 ceramics
(Oxford : Elsevier Sci Ltd, 2007)
Ceramic materials with a perovskite related structures such as non-doped and doped barium titanate ceramics are attracting much interest for their application as capacitor dielectrics, resistors, thermal sensors, etc. Since ...
Structural and electrical properties of sintered zinc-titanate ceramics
(Elsevier, 2009)
The aim of this work was an investigation of structural and electrical properties of sintered zinc-titanate ceramics obtained by mechanical activation. Mixtures of ZnO and TiO2 were mechanically activated in a planetary ...
