Method of forming a ceramic product |
| abstract |
A method of forming a dense ceramic product comprised of silicon nitride and silicon oxynitride or aluminium substituted derivatives of either in which silica is subjected to a controlled partial carbothermal reduction process in the presence of nitrogen to produce residual silica and silicon nitride, fabricating the resulting material into the desired shape and heating in a nitrogen atmosphere at a temperature of from 1400°C to 2000°C with or without pressure to form the product. The silica may conveniently be derived from pyrolysed rice hulls. The product may also comprise silicon carbide, which may be derived from the carbothermal reduction, and a glassy phase. |
