Sintering of silicon nitride using Be additive |
| 摘要 |
A particulate dispersion of silicon nitride and beryllium additive is formed into a green body and sintered at a temperature ranging from about 1900 DEG C. to about 2200 DEG C. in a sintering atmosphere of nitrogen at superatmospheric pressure producing a sintered body with a density ranging from about 80% to about 100%.
