Preparation method of multiphase composite reinforced silicon carbide ceramic
The invention provides a preparation method of multiphase composite reinforced silicon carbide ceramic. The invention also provides a multiphase composite reinforced silicon carbide ceramic. The multiphase composite reinforced silicon carbide ceramic comprises silicon carbide, in-situ generated nanometer SiC particles dispersed in the silicon carbide, mullite whiskers, and rod-like alumina and/or sheet-like alumina dispersed in the silicon carbide. According to the multi-phase composite reinforced silicon carbide ceramic provided by the invention, the rod-shaped aluminum oxide and/or sheet-shaped aluminum oxide are/is dispersed in the silicon carbide ceramic, and the nanometer SiC particles and mullite whiskers are generated in situ, so the strength and toughness of the silicon carbide ceramic are greatly improved.
本发明提供了一种多相复合增强碳化硅陶瓷的制备方法。本发明还提供了一种多相复合增强碳化硅陶瓷，包括碳化硅，分散于碳化硅内部的原位生成的纳米SiC颗粒、莫来石晶须，以及分散于碳化硅内部的棒状氧化铝和/或片状氧化铝。本发明提供的多相复合增强碳化硅陶瓷，一方面将棒状氧化铝和/或片状氧化铝分散于碳化硅陶瓷中，另一方面在原位生成纳米SiC颗粒、莫来石晶须，大大提高了碳化硅陶瓷的强度和韧性。
