Results show that for sintering temperatures up to 400°C the samples have a fractal pore size distribution. As the sintering temperature increases, a structural rearragement occurs, allowing an increase of the efficiency of particle packing and the reduction of fractality. Above 400°C, the pore size growth associated with grain coalescence is the main structural change observed as the sintering temperature increases. © 1995.217-225engFractal structureMicropore evaluationSinteringSnO2 sol-gel powderArtigo10.1016/0927-7757(95)03084-QAcesso restrito2-s2.0-33750403361558429868187086599712025852869670000-0002-8356-8093
