| titleOfInvention | Improved sintering process and novel ceramic material |
| abstract | A process for the sintering of a body comprising silicon carbide and a boron-containing material, which comprises heating the body to an effective sintering temperature in the presence of nitrogen; removing the nitrogen by evacuation to a pressure of less than 10- 2 mbar; and continuing the sintering under vacuum or in the presence of an inert gas other than nitrogen. The invention also describes a sintered body comprising silicon carbide and a boron-containing material, having a density of at least 96% of its theoretical maximum density, in which the body contains less than 0.7% w of free carbon, and has a mean silicon carbide grain size of less than 5 microns. |
