METHOD FOR PRODUCING POLYCRYSTALLINE SILICON NITRIDE BODIES |
| 摘要 |
Polycrystalline ceramic bodies of Si3N4when prepared to obtain an intergranular phase which is substantially crystalline, exhibits significantly improved mechanical strength at elevated temperatures above 1,000 DEG C. up to 1600 DEG C. over bodies having glass-containing intergranular phases. |
