Abstract
Sol-gel synthesized SnO2 nanoparticles with an average size of 20.0 nm obtained at 100º C were gradually annealed to 800º C in air for 60 minutes. Crystal density, lattice volume and microstrain are found to be nearly constant with annealing temperature, which confirm the formation of monophase SnO2. The prepared powders were characterized for their structural, morphological, and electrical properties. Spherical particles in the nanoscale level, with the size increasing with temperature are observed from XRD, SEM and TEM results.
