The invention provides boron carbide reinforced silicon carbide ceramic and a preparation method thereof. The silicon carbide ceramic has the advantages of high hardness, wear resistance, corrosion resistance and the like, and the preparation cost is lower. However, the fracture toughness of single silicon carbide ceramic is low. According to the invention, the mechanical properties of the silicon carbide ceramic are improved through the improvement of the batch and the preparation method.
本发明提供一种碳化硼增强碳化硅陶瓷及制备方法。碳化硅陶瓷具有硬度高，耐磨、耐腐蚀等优点，切制备成本较低。但单一的碳化硅陶瓷断裂韧性较低。低温强度不高，本发明通过配合料的改善和制备方法，提高了碳化硅陶瓷的机械性能。
