FASERVERSTAERKTE KERAMIKWERKSTOFFE. |
| 摘要 |
<p>The present invention provides fiber-reinforced ceramics containing at least one member of fibers and whiskers as distributed in a sintering ceramic matrix, which comprises the ceramic matrix being composed mainly of SiC, Si3N4 and Si6-zAlzOzN8-z, where 0<z</=4, the fibers and the whiskers being composed of at least one of SiC, Si3N4 and Si6-zAlzOzN8-z, where 0<z</=4, and a coating film of C, B or BN being provided on the surfaces of the fibers and the whiskers. The fiber-reinforced ceramics have a high fracture toughness, Klc, and a high bending strength, particularly klc of at least 10 MN/m3/2 and a bending strength of at least 50 kg/mm2.</p> |
