Morphology investigation of mechanically activated ZnO-SnO2 system
(Elsevier Sci Ltd, Oxford, 2008)
Powder mixtures of zinc oxide and tin oxide in the molar ratio, ZnO:SnO2 = 2: 1, were mechanically activated in a planetary ball mill in the time intervals of 0-160 min. The adsorption-desorption isotherms, specific surface ...
Structural and electrical properties of ZnO varistors containing different spinel phases
(Elsevier Sci Ltd, Oxford, 2001)
Structural and electrical properties of ZnO varistors were investigated as a function of spinel composition. Six varistor mixtures differing only in chemical composition of spinel, were prepared by mixing separately ...
