Abstract

Nanocrystalline powders of two indium tin oxide (ITO) polymorphs - rhombohedral and cubic - were prepared by a coprecipitation process. The temperature and aging time of precipitates after co-precipitation were controlled to obtain selectively the two different crystal structures. X-ray diffraction and transmission electron microscopy were used to characterize the powders. The electrical conductivity of the two ITO powders was determined by the powder solution composite method. The conductivities obtained were 0.26±0.04 and 0.65±0.17 S/cm for the rhombohedral and cubic ITO samples, respectively, the first such report for the rhombohedral phase.
