在1000 ~ 1500°C范围内研究了SnO_2在In_2O_3中的固溶度。使用In 2 O3粉末和锡醇盐溶液以及铟和锡醇盐的混合溶液制备样品。X射线衍射分析显示，在1000、1300、1400和1500°C下，SnO 2在In 2 O3中的溶解度极限分别为0.5%、2%、3.5%和5%。固溶体的密度与基于间隙氧化物离子作为所得缺陷的计算一致。Rietveld分析表明，SnO 2的低溶解度是由于较小的尺寸相比，氧化物离子的离子半径的间隙网站。
Solid solubility of SnO2 in In2O3 was investigated in the interval between 1000 to 1500°C. Samples were prepared using In2O3 powder and tin alkoxide solution, as well as mixed solution of indium and tin alkoxides. X-ray diffraction analysis revealed a solubility limit of SnO2 in In2O3 0.5, 2, 3.5, and 5% at 1000, 1300, 1400 and 1500°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.
