  • Preparation of barium titanate aerogels by supercritical drying with CO2 and propane
    Novak, Zoran ...
    BaTiO3 powders from sol-gel derived gels were prepared using two different drying methods. In addition to the conventional drying of gels in air at 90°C the supercritical CO2 drying method was also ... used. The results have shown that the properties of BaTiO3 powder produced by supercritical drying with CO2 are better. The grain surface is less contaminated as a result of the supercritical drying and the microstructre development during sintering leads to a homogeneous fine grained microstructure.
