  • Supercritical CO2 drying of barium titanate sol-gel derived gels [Elektronski vir]
    Novak, Zoran ...
    Two different drying methods, conventional drying of gels in air at 90*C and supercritical 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 desintegration products which are formed during drying. As a result, the sintering of a sample prepared from the CO2-dried powder leads to a homogenuous and fine-grained microstructure.
