WO3 and ZnO-doped SnO2 ceramics as insulating material
(Elsevier B.V., 2006-01-01)
SnO2 ceramics doped with ZnO and WO3 were prepared by mixed oxide method. The effect of ZnO and WO3 additives could be explained by the substitution of Sn4+ by Zn2+ and W6+. The addition of WO3 inhibits the grain growth ...
