Additions of 0.5 to 2.0 mol% of CoO or MnO{sub 2} onto SnO{sub 2} promote densification of this oxide up to 99% of theoretical density. The temperature of the maximum shrinkage rate (T{sub M}) and the relative density in the maximum densification rate ({rho}*) during constant sintering heating rate depend on the dopant concentration. Thus, dopant concentration controls the densifying and nondensifying mechanisms during sintering. The densification of SnO{sub 2} with addition of CoO or MnO{sub 2} is explained in terms of the creation of oxygen vacancies.
