摘要：

Solid solubility of SnO2 in In2O3 was investigated in the interval between 1000 to 1500 degrees C. Samples were prepared using In2O3 powder and tin alkoxide solution, as well as mixed solution of indium and tin alkoxides. Xray diffraction analysis revealed a solubility limit of SnO2 in In2O3 0.5, 2, 3.5, and 5% at 1000, 1300, 1400 and 1500 degrees C, respectively. The densities of the solid solutions agreed with calculations based on interstitial oxide ions as a resultant defect. Rietveld analysis revealed that the low solubility of SnO2 was due to the smaller size of the interstitial sites compared to the ionic radius of the oxide ion.
