摘要
超硬材料的合成是目前材料科学研究领域的热门课题之一。近年来，由于碳基和硼基超硬材料的理论设计和发现，引起了人们在实验和理论上对硬度与金刚石接近，甚至超过金刚石的材料研究兴趣。在Ｂ－Ｃ－Ｎ系超硬材料中，除了金刚石和立方氮化硼（ｃ－ＢＮ）以外，β－Ｃ_３Ｎ_４、立方氮碳化硼以及富勒烯等材料，也正日益受到国际材料界的重视。本文就Ｂ－Ｃ－Ｎ系超硬料的最新研究进展做一综述。
The synthesis of superhard materials is an interesting research subject in the field of materials science. Recently, experimental and theoretical research activities on materials with an hardness comparable to or higher than diamond have been stimulated by the postulation and discovery of novel carbon-and boron-based superhard materials. Besides diamond and c-BN, β－ C3N4, c-BCN and fullerenes are also potential candidates for superhard materials. This review deals with the latest research progress in the field of novel carbon- and boron-based superhard materials.
