摘　　要：碳化硼陶瓷具有高硬度、高弹性模量、耐磨损、耐腐蚀等优点,是一种综合性能优异的结构材料。碳化硼陶瓷可通过有效添加剂、适当的温度与压力等条件实现致密化烧结,从而提高其综合性能,因此碳化硼的致密化烧结是其关键技术。本文论述了碳化硼陶瓷致密化烧结工艺的基本原理及烧结方法,在此基础上总结了碳化硼陶瓷在陶瓷装甲、核能和耐磨技术等重要领域的应用。Boron carbide ceramics are typical structural materials with excellent comprehensive properties, due to their high hardness, high elastic modulus, excellent resistance to wear and corrosion, as well as other advantages. The densification of boron carbide ceramics can be realized by effective additives, appropriate temperature and pressure to improve their mechanical behaviors. Thus, the sintering and densification are the key steps in the entire preparing process. Here, the basic principle and routes of the sintering of boron carbide ceramics are summarized, and their applications in the field of armor, nuclear power, and abrasives are presented.
