Influence of MgO addition on the synthesis and electrical properties of sintered zinc-titanate ceramics
(Elsevier Science Sa, Lausanne, 2009)
Starting mixtures of ZnO, TiO(2) and MgO (0, 1.25 and 2.5 wt.% MgO) powders were mechanically activated for 15 min in a planetary ball mill. The powders obtained were sintered non-isothermally to temperatures between 800 ...
Mechanochemically assisted solid-state and citric acid complex syntheses of Cu-doped sodium cobaltite ceramics
(Elsevier Science Sa, Lausanne, 2015)
In the last decade, the sodium cobaltite ceramic became a promising candidate for potential thermoelectric applications, because of its large thermopower and low resistivity. In this work, polycrystalline samples of ...
