Abstract
The chemical properties and electrical transport properties of SnOx do ped In2O3 (ITO) and their differences between single crystals prepared by chemical vapour transport, fine powders (150...200 nm particle siz e) and weakly sintered ceramics (1100 degrees C, 24h, about 50% of the oretical density) were reported. In single crystals the minimal resist ivity is found at the solubility limit of SnOx (8.2 mol%), whereas in ceramics and fine powders a minimum occurs at lower concentrations whi ch is connected with a strong surface segregation of SnOx.
