Abstract

Thermogravimetric measurements were conducted on undoped, Nb⁵⁺ or Ta⁵⁺ donor-doped, and Al³⁺ acceptor doped rutile at 1000°C and 105-10-7 Pa oxygen activity. Nb⁵⁺ or Ta⁵⁺ doped rutile was counter doped by Al³⁺ in order to identify the role of Al³⁺ acceptor and its effect on donor doped rutile. Our results show that both dopants enter the lattice substitutionally for Ti⁴⁺, that Al³⁺ is as effective an acceptor as Nb⁵⁺ or that Ta⁵⁺ is effective as a donor, and the compensation occurs on a one-to-one basis. Earlier reports indicate that Al³⁺ is at best 50-70% efficient as an acceptor. © 1991.
