  • Biodegradable and bioactive glass-ceramics, and method for fabricating the same
    Patent number: 7582310
    Abstract: Disclosed herein is a biodegradable and bioactive glass-ceramic fabricated by mixing a slowly biodegradable glass-ceramic and a highly biodegradable glass-ceramic in a predetermined mixing ratio wherein the bioactivity is maintained to be constant, and the biodegradation rate is controlled by the mixing ratio. The biodegradable and bioactive glass-ceramic is fabricated from a composition consisting of calcium oxide (CaO), silica (SiO2), boron oxide (B2O3), magnesium oxide (MgO), calcium fluoride (CaF2) and phosphorus pentoxide (P2O5).
    Type: Grant
    Filed: August 27, 2003
    Date of Patent: September 1, 2009
    Assignee: Seoul National University Industry Foundation
    Inventors: Hyun Seung Yu, Kug Sun Hong, Hwan Kim, Dong Ho Lee, Choon Ki Lee, Bong Soon Chang, Deug Joong Kim, Jun Hyuk Seo, Jae Hyup Lee, Ki Soo Park
  • Self-foamed porous ceramic composition and method for making porous ceramic using the same
    Patent number: 7169721
    Abstract: Disclosed herein are a self-foamed porous ceramic composition and a method for making a porous ceramic using the self-foamed porous ceramic composition. The self-foamed porous ceramic is obtained by fabricating a glass consisting of 41˜47 mole % of calcium oxide (CaO), 41˜47 mole % of silica (SiO2) and 6˜18 mole % of borate (B2O3), pulverizing the glass into a finely-divided glass powder having an average particle size of 1˜10 ?m, molding the glass powder, and sintering the molded glass powder.
