  • Forsterite and method for making
    Patent number: 8691172
    Abstract: High temperature fusion of olivine to produce forsterite in the presence of a reducing agent such as carbon can produce improved refractories when in addition to MgO additional, particular oxidation and/or oxidative reaction environments beyond the use of Carbon are employed.
    Type: Grant
    Filed: February 25, 2009
    Date of Patent: April 8, 2014
    Assignee: KBI Enterprises, LLC
    Inventors: Dale F. DeSanto, Robert A. Pattillo
  • Cement-free refractory
    Patent number: 8618006
    Abstract: A cement free refractory mixture contains aluminum oxide, silicon carbide, fumed silica, aluminum metal, an anti-oxidant, reactive alumina, and a carbon-bearing material. The mixture can be formed by conventional techniques to create refractory articles to contain or direct the flow of liquid metals. Refractory articles formed by the mixture do not require firing to achieve an initial cure.
    Type: Grant

  • CEMENT-FREE REFRACTORY
    Publication number: 20100009840
    Abstract: The present invention describes a cement free refractory mixture. The mixture comprises a pH buffer and a component containing a metal or fumed silica. Water may impart good flow characteristics to the mixture and can produce an effective low temperature cure. At elevated temperatures, an article formed using this mixture has superior refractory and physical properties.
