J. Kemmler, S. Pokhrel, L. Mädler, N. Barsan & U. Weimar
In4Sn3O12 is considered as a high temperature phase of the binary In2O3 - SnO2 mixture. As shown by Isomäki et al, this specific phase is stable in the temperature region of about 1.600 °C to, depending on the mole fraction, 1.950 °C.[1] Furthermore, this phase can be found throughout almost the whole range of the mole fraction (0,1-~1 SnO2). As a matter of fact, by applying Flame Spray Pyrolysis (FSP) to synthesize this ITO-like metal...
