Abstract

The phase development and electrical characteristics of ln ₂O₃(ZnO)₂ were examined when SnO₂ (Sn+4) and ZnO (Zn+2) in a ratio of 1:1 were simultaneously substituted for ln₂O₃. When ln₂O₃(ZnO)₂ was sintered it was separated into ln₂O₃ and ln ₂O₃(ZnO)₃ phases and the co-substituent of (Zno^Sno^O)! 5 was soluble in both ln₂O₃ and ln ₂O₃(ZnO)3. As the amount of (Zn_0.5Sn _0.5O)_1.5 increased up to 15 at%, which is regarded as the solubility limit, both ln₂O₃ and ln₂O ₃(ZnO)₃ phases still maintained. The grain size of the sintered body was almost invariant regardless of the amount of (Zn _0.5Sn_0.5O)_1.5 within the solubility limit. The electron mobility was constant while the carrier concentration declined slowly, which resulted in a decrease in conductivity. When the (Zn_0.5Sn _0.5O)_1.5 was added beyond the solubility limit, a new phase of Zn₂SnO₄ was produced, which reduced the volume fraction of the ln₂O₃ and ln₂O ₃(ZnO)₃ phases as well as electrical conductivity.
