  • Coal based silicon carbide foam
    Patent number: 11685662
    Abstract: A method for producing silicon carbide directly from comminuted coal and a silicon precursor is described. The process includes coating comminuted coal with a silicon precursor and heating the silicon precursor coated comminuted coal to initially form polymerized preceramic silicon-carbon foam and then further heating to form silicon carbide foam.
    Type: Grant
    Filed: June 17, 2020
    Date of Patent: June 27, 2023
    Assignee: Touchstone Research Laboratory, Ltd.
    Inventors: Dwayne R. Morgan, Frederick H. Wade
  • Carbon foam based silicon carbide
    Patent number: 11685661
    Abstract: A method for producing a siliconized carbon foam with regions of silicon carbide directly from comminuted coal and particulate silicone resin precursor is described. The process includes blending a comminuted coal and particulate silicone resin and heating the blended mixture to form a siliconized carbon foam and then further heating to form regions of silicon carbide.

  • Carbon foam based silicon carbide
    Patent number: 11186522
    Abstract: Producing silicon carbide carbon foam is described. The process includes filling the pores of a carbon foam with a polysiloxane resin and heating the impregnated carbon foam to high temperatures to convert the silicon in the polysiloxane resin to silicon carbon within the carbon foam.
