Microstructural, Thermoelectric and Mechanical Properties of Cu Substituted NaCo2O4
(MDPI, 2022)
Polycrystalline samples of NaCo2−xCuxO4 (x = 0, 0.01, 0.03, 0.05) were obtained from powder precursors synthesized by a mechanochemically assisted solid-state reaction method (MASSR) and a citric acid complex method (CAC). ...
ZnO varistors prepared by direct mixing of constituent phases
(Japan Inst Metals & Materials, Sendai, 2000)
ZnO varistors with non-linearity coefficients reaching 50 and low values of the leakage current (similar to0.01 A/m(2)), were obtained by a method referred to as "direct mixing of constituent phases". The method is based ...
