[ ] with HC network hardware diamond technology becomes more mature as well as China's rapid economic growth, our country in diamond tool manufacturing technology with more accumulation and progress, have a strong manufacturing capability. Because of China's labor cost advantage, together with R & D late catch-up situation, causes our country enterprise on the product price has obvious advantages. The rapid growth of market demand, around the diamond tools enterprises have started, and the emergence of a number of international competitive advantage of enterprises. China has become the world's important diamond tools production country, application and exporting countries, the annual output value of more than 10 billion yuan.
In 1, diamond in the emerging field of application is expected to further expand with the diamond grade rising, its excellent performance is expected in the high-tech fields to be more widely applied, such as may be used for aircraft instrument bearing, radar wave, optical devices, such as high energy gas velocity precision instrument processing; can be used for single crystal silicon polycrystalline silicon film thickness 0.1-0.2mm, cutting, grinding, satellite solar panel and high precision machining; can be used for computer chip LSI fine precision cutting, notching, backside thinning, nano diamond polishing processing; high purity large single crystal diamond can also be used for production of dynamic compression test of high strength optical window, very environment some device window hole and study of nuclear fusion energy component etc.. The developed countries in the world are all include diamond, super-hard materials and products as the focus of development, superhard materials and products in the research and application level to some extent represents a country's level of development of science and technology.
In 2, our country man-made diamond market of high quality diamond with a lower proportion of added value, enhance space large current domestic superhard materials and products production at about 1: 3 to 1 : 6 between, with the downstream products superhard materials market grows in size, superhard materials, the market prospects are very broad. High grade diamond market demand for the entire market ratio of about 60% to 70%, according to the current domestic technical level of production of high grade diamond diamond products, the proportion is low, only 25% ~ 30%, and the 60% market demand relatively, breach is 30% ~ 35%. As a result of our country diamond products overall technology and quality level lags behind that of developed countries, used in electronics, automotive, home appliances, such as CNC machining industry with high-end products more than 90% of dependence on import. Therefore our country in the field of high-end super-hard materials the development of large space. In recent years, artificial diamond application object and the application domain expands unceasingly, the market demand is exuberant, showing a sustained rapid growth trend.
In 3, the future of diamond growth in demand, prices rose steadily over the next few years our country man-made diamond market demand still can be maintained at a compound annual growth above 15%. According to Industry Association statistics, 2001 - 2009 domestic synthetic diamond production and sales volume by 1600000000 carat rose to 5400000000 carat, compound annual growth rate of about 16.4%. The next few years our country man-made diamond market demand still can be maintained at an average annual growth of more than 10%, is expected in 2012 the domestic market demand can reach 7000000000 carat. With the domestic diamond industry technology progress and improving the quality of products, our country man-made diamond products gradually by the international customers, according to Industry Association statistics, 2001 - 2008 China's diamond exports from 153000000 carat rose to 1350000000 carat, compound annual growth rate of 37%. By virtue of China's diamond industry production capacity and price advantage, our country man-made diamond and its products exports will continue to maintain rapid growth trend.
In conclusion, with the development of technology of artificial diamond, diamond tools, artificial diamond in the new materials, new technology, new equipment is gradually applied in synthetic diamond industry in China and its own advantages, there is reason to believe that China 's diamond market in the next few years will usher in the golden period of development, maintain high speed development trend.
