20080234122 | A SINTERED REFACTORY MATERIAL BASED ON SILICON CARBIDE WITH A SILICON NITRIDE BINDER - A sintered material based on silicon carbide (SiC) reactively sintered between 1,100° C. and 1,700° C. to form a silicon nitride binder (Si | 09-25-2008 |
20090035558 | SINTERED CERAMIC PRODUCT HAVING A NITROGENOUS MATRIX WITH IMPROVED SURFACE PROPERTIES - The sintered ceramic product comprises a granular material bound by a nitrogenous mold. According to the invention, at least one anti-dust agent selected among calcium and boron exists in a surface layer of the product, the mass ratio of all the anti-dust agents in the surface layer being greater than that measured underneath this layer. This product advantageously has a reduced ratio of non-adherent particles to its surface. | 02-05-2009 |
20090312173 | VOLUME-CHANGE RESISTANT SILICON OXY-NITRIDE OR SILICON OXY-NITRIDE AND SILICON NITRIDE BONDED SILICON CARBIDE REFRACTORY - A reaction sintered silicon carbide-based product, including a silicon carbide component, a bond component, wherein the bond component includes silicon oxynitride in excess of any silicon nitride of the bond component, and at least one boron component residual to an amount present prior to reaction sintering to cause increased resistance of the reaction sintered silicon carbide-based product to volume change under oxidative stress, and methods of making the same. | 12-17-2009 |
20110024956 | SINTERED REFRACTORY MATERIAL BASED ON SILICON CARBIDE WITH A SILICON NITRIDE BINDER - A sintered material based on silicon carbide (SiC) reactively sintered between 1,100° C. and 1,700° C. to form a silicon nitride binder (Si | 02-03-2011 |
20110175264 | High Toughness Ceramic Composites - A method of forming a sintered silicon carbide body includes mixing silicon carbide powder having an oxygen content of less than about 3 wt % and having a surface area in a range of between about 8 m | 07-21-2011 |
