摘要
Superhard materials such as diamond or cubic boron nitride are widely used in industry for fast machining and drilling. A great challenge to scientists is to make a material which could be harder than diamond. A short review of the compounds predicted to be superhard is made. A new approach based on recent experimental high-pressure results is to consider heavier-atom compounds crystallizing in dense structures; possible new materials are proposed.
