SiC-Si3N4 Composite system for special heat-resisting ceramic materials and its fabrication method |
摘要 |
A SiC-Si3N4 composite system for special heat-resisting ceramic materials which is fabricated by firing in a nitriding gas atmosphere a green compact prepared from and composed of, as starting materials, silicon powder and an organic silicon polymer containing carbon and silicon atoms as the major skeletal components, whereby said composite system, as a final fired compact has an interwoven texture of SiC and Si3N4 with sufficient micro gaps to absorb thermal stresses, wherein the quantitative ratio by weight of SiC to Si3N4 in said composite system being in the range of 5%-20%:95%-80%.
