  • Preparation of BaTiO3 powders using supercritical CO2 drying of gels
    Novak, Zoran ...
    Two different drying methods, conventional drying of gels in air at 90°C and supercritcal CO2 (SC-CO2) drying, were used to prepare BaTiO3 powders from sol-gel derived gels. The results reveal that ... powders prepared by supercritical drying with CO2 are less contaminated with the organic disintegration products which are formed during drying. As a result, the sintering of a sample prepared from the CO2-dried powder leads to a homogeneous and fine-grained microstructure.
