Advantage of future development of synthetic diamond


With the continuous development of synthetic diamond technology, diamond tools and synthetic diamonds are gradually applied in new materials, new processes and new equipment, and China's own advantages in the synthetic diamond industry, there is reason to believe that China's synthetic diamond market will usher in the golden development period in the next few years and maintain a high-speed development trend.
 
1, the future diamond demand growth, the price of a steady rebound in the next few years, China's synthetic diamond market demand can still maintain an average annual compound growth of more than 15%. According to industry association statistics, 2001-2009 domestic synthetic diamond production and sales increased from 1.6 billion carats to 5.4 billion carats, an average annual compound growth of about 16.4 percent. In the next few years, the market demand for synthetic diamond in China can still maintain an average annual growth of more than 10%, and the domestic market demand is expected to reach 7 billion carats in 2012. With the technological progress of the domestic synthetic diamond industry and the improvement of product quality, China's synthetic diamond products have gradually been recognized by international customers. According to the statistics of the industry association, the number of synthetic diamond exports in China increased from 0.153 billion carats to 1.35 billion carats from 2001 to 2008, with an average annual compound growth rate of 37%. With the production capacity and price advantage of China's synthetic diamond industry, China's synthetic diamond and its products exports will continue to maintain a rapid growth trend.
 
2, China's synthetic diamond market high-grade diamond proportion is low, the added value of the space to enhance the current domestic superhard materials and products output value of about 1:3~1:6, with the downstream superhard materials products market size continues to grow, the market prospects of superhard materials is very broad. The market demand for high-grade diamonds accounts for about 60% to 70% of the total market. According to the current domestic technical level of diamond products, the proportion of high-grade diamonds is low, only about 25% to 30%, compared with 60% of the market demand, the gap is 30% to 35%. As the overall technology and quality level of diamond products in China lags behind that of developed countries, more than 90% of high-end products used in electronics, automobiles, home appliances, CNC machining and other industries rely on imports. Therefore, China has a large space for development in the field of high-grade superhard materials. In recent years, the application objects and application fields of synthetic diamond have been expanding, and the market demand has become more vigorous, showing a trend of sustained and rapid growth.
 
3, the application of synthetic diamond in the field of emerging industries is expected to further expand with the continuous improvement of synthetic diamond grade, its excellent performance is expected to be more widely used in the field of high and new technology, such as aviation instrument bearings, radar waveguides, optical devices, high-energy smoke speed device and other precision instruments processing; it can be used for cutting and grinding monocrystalline silicon and polycrystalline silicon 0.1-0.2mm thick sheets, high-efficiency and precision processing of satellite solar panels, etc. It can be used for micro-precision cutting, grooving, back thinning, nano-diamond polishing and other processing of large-scale integrated circuits such as computer chips. High-purity large single crystal diamond can also be used to make high-strength optical windows for dynamic compression tests, window holes for some devices in extraordinary environments, and components for nuclear fusion energy research, etc. The developed countries in the world all regard superhard materials and products including synthetic diamond as the development focus. The research and application level of superhard materials and products represents the level of scientific and technological development of a country to some extent.
 
With the increasing maturity of synthetic diamond technology and the rapid take-off of China's economy, China has made more accumulation and progress in diamond tool manufacturing technology, and has a strong manufacturing capacity. Due to the huge advantages of Chinese enterprises in labor costs, coupled with the late catch-up trend in technology research and development, Chinese enterprises have obvious advantages in product cost performance. With the rapid growth of market demand, diamond tool enterprises all over the country have been launched, and a number of enterprises with international competitive strength have emerged. China has become an important producer, application and exporter of diamond tools in the world, with an annual output value of more than 10 billion yuan.
