只是单一成分的材料要满足严酷性能的要求一般是困难的。因此根据材料设计、膜设计等将各种单一组分的材料进行复合化,或开发具有必要特性的新型复合材料或化合物是十分必要的。氮化硼、碳化硼或硼类陶瓷作为高温材料是最有意义的。碳氮化硼(BNC)可以说是氮化硼(BN)和碳化硼(B、C)的复合产物,它具有以氮化硼(h-BN)为母相的六方晶格。碳氮化硼具有超过氮化硼或氮化硅的极
It is generally difficult to just meet the stringent performance requirements of a single component of the material. Therefore, it is necessary to combine various single-component materials according to material design, film design, etc., or to develop novel composite materials or compounds having the necessary characteristics. Boron nitride, boron carbide or boron-based ceramics are the most significant materials for high-temperature applications. Boron carbonitride (BNC) can be said to be a composite product of boron nitride (BN) and boron carbide (B, C) having a hexagonal lattice with boron nitride (h-BN) as the parent phase. Boron carbonitride has poles over boron nitride or silicon nitride
