Abstract

We have systematically investigated the influence of various parameters (pressure, temperature, time, sample size) on the hot pressing process of TiO2 nanoceramics. This study is backed by thermodilatometric experiments and microscopic observations of the microstructure. Impedance spectra of TiO2 nanoceramics with different porosity are also presented.
