Time, temperature and sintering atmosphere have large influence on grain growth and low influence on densification of this oxide. Surface diffusion is the dominant mechanism up to 1200 °C and evaporation-condensation is dominant above 1200 °C. The maximum linear shrinkage observed was about 2.0% and attributed to structural rearrangement of particles due to high capillary stresses developed with neighboring particles. © 1999 Trans Tech Publications.134-140engAtmosphereSinteringSnO 2Artigo10.4028/www.scientific.net/MSF.299-300.134WOS:000079831600018Acesso restrito2-s2.0-4444257922
