The Sb 2 O 3 Addition Effect on Sintering ZnO and ZnO+Bi 2 O 3
The effects of adding minute quantities of Sb 2 O 3 when sintering ZnO and ZnO+Bi 2 O 3 (0.5 mol%) were studied. To prevent non-uniform distribution of the additive, dilute solutions of Sb-salts were used instead of solid Sb 2 O 3 . Very small quantity additions of Sb 2 O 3 retarded sintering of bot...
