  • Mesostructured oxide ceramics and their synthesis method
    Patent number: 6841143
    Abstract: This invention provides mesostructured oxide ceramics and a synthesizing method thereof, the synthesizing method employs a water-based solvent containing a metallic salt or metal complex as the ceramics precursor, template formed from an organic compound or the association thereof, and a precipitant, wherein mesostructured oxide ceramics are obtained from self-assembled oxide ceramics and organic substance by directly extracting oxide ceramics at a low temperature of 200° C. or less by utilizing a homogenous precipitation reaction from said ceramics precursor under the coexistence of a nanometer-sized template in the solvent, and separating and collecting the obtained precipitation, and mesostructured oxide ceramics is prepared by employing the synthesizing method described above.
    Type: Grant
