Abstract
Titania nanopovvders obtained by hydrolysis of titanium alkoxides and consecutive hydrothermal treatment were compacted and sintered. The influence of preparation conditions (alkyl, pH of hydrolysis, temperature of hydrothermal treatment, compacting pressure, sintering temperature) on the porosity of powders, compacts and sintered bodies was investigated by nitrogen sorption and mercury intrusion. Optimum conditions are derived to prepare high-density ceramics at relatively low sintering temperature.
