  • Open-cell glass crystalline porous material
    Patent number: 6667261
    Abstract: An open-cell glass crystalline porous material made from hollow microspheres which are cenospheres obtained from fly ash, having an open-cell porosity of up to 90 vol. % is produced. The cenospheres are separated into fractions based on one or more of grain size, density, magnetic or non-magnetic, and perforated or non-perforated. Selected fractions are molded and agglomerated by sintering with a binder at a temperature below the softening temperature, or without a binder at a temperature about, or above, the softening temperature but below the temperature of liquidity. The porous material produced has an apparent density of 0.3-0.6 g/cm3, a compressive strength in the range of 1.2-3.5 MPa, and two types of openings: through-flow wall pores in the cenospheres of 0.1-30 micrometers, and interglobular voids between the cenospheres of 20-100 micrometers.
    Type: Grant
    Filed: May 15, 2002
    Date of Patent: December 23, 2003
    Assignee: The United States of America as represented by the United States Department of Energy
    Inventors: Alexander G. Anshits, Olga M. Sharonova, Tatiana A. Vereshchagina, Irina D. Zykova, Yurii A. Revenko, Alexander A. Tretyakov, Albert S. Aloy, Rem I. Lubtsev, Dieter A. Knecht, Troy J. Tranter, Yevgeny Macheret
