高速发展的中国超硬材料

中国经过40年超硬材料艰辛的研发历程，现在全国超硬材料已由开始的研制开发，发展成今日的超硬材料行业，年产量已达20亿ct以上(还有信息说达25亿ct左右)。它已是国民经济发展高新技术产业不可缺少的重要组成部分。同样在发展探矿工程、岩土工程及多种金刚石钻探、多种特种钻探方面，也是无可替代的重要磨料，这方面的信息对我们指导发展近代探矿工程、岩土工程是有意义的。

Super-hard Material Develops at High Speed in China

Super-hard materials have been developed for forty years in China. In the very beginning the super-hard materials were studied only in lab. Now they grow into a super-hard material industry. The yearly output has been over two billion ct. Some information sources said the yearly output has reached about two billion five hundred million ct. The super-hard material industry has become an important part that is absolutely necessary to develop our country''s high technology. Meanwhile they are very important mill materials which were no substitute for in drilling industry. The information on this aspect is of significance for our developing modern exploration engineering and rock and soil engineering.
