  • Ceramic body comprising silicon carbide and method of forming same
    Patent number: 9540283
    Abstract: A method of forming a ceramic body including forming a mixture made of at least a first powder material (PM1) including carbon having a first average particle size (PS1), a second powder material (PM2) including carbon and different than the first powder material, the second powder material having a second average particle size (PS2) less than the first average particle size (PS1), and an aluminum content (AC2) greater than the aluminum content (AC1) of the first powder material, and further including forming a green body from the mixture, and sintering the green body and forming a ceramic body having a first type of grain having an average grain size of not greater than about 8 times the first average particle size (PS1).

  • METHOD OF FORMING A POROUS SINTERED CERAMIC BODY
    Publication number: 20140291898
    Abstract: A porous sintered silicon carbide body that includes a ceramic and a solid lubricant and methods of making thereof are described. The porous silicon carbide body can be a seal. The porous sintered silicon carbide body defines pores that can have an average pore size in a range of between about 20 ?m and about 40 ?m, and a porosity in a range of between about 1% and about 6% by volume.
