A phenomenon of bilevel solubility was observed in a TiO2-doped (2.0 wt%) alumina with bimodal microstructure sintered in N2. Surface contributions to dopant signals in individual grains were identified and removed, using a spatially resolved energy dispersive spectroscopy analysis. Two levels of solubility, 1.005 ± 0.166 and 0.504 ± 0.082 mol% of TiO2 in A12O3, were obtained for anisotropic and equiaxed grains, respectively. No grain size dependence of solubility was found, but segregation of SiO2 to boundaries with the anisotropic grains was observed. This phenomenon was explained by the incorporation of Ti3+ into the A12O3 lattice during the abnormal grain growth caused by SiO2 liquid under a reducing atmosphere.
