Abstract

The present paper reports experimental data on the effect of processing of undoped polycrystalline TiO₂ on the microstructure. The processing included the precipitation of TiO₂ powder, obtained by adding water to Ti isopropoxide (99-999%)-ethanol mixture, drying, pressing and sintering. The applied procedures of pressing included both cold isostatic pressing and high temperature isostatic pressing. The obtained SEM micrographs are considered in terms of the effect of the applied processing procedure on microstructure and defect chemistry. The processing including sintering at 1688 K and subsequent high temperature isostatic pressing at low oxygen activity resulted in maximum density.
