Grain Growth Rate in SnO2 Ceramics Doped with Varying Ratios of Nb2O5/CoO
In this study, aliovalent ions of Nb2O5 and CoO were co-doped in SnO2 with different Nb2O5/CoO ratios and the grain growth rate of SnO2 was examined. The maximum grain growth rate was observed to be around Nb2O5/CoO = 0.25. Here, the results will be discussed in connection with the defect concentration and the change in diffusion rate-determining species with different Nb2O5/CoO ratios.
