Synthetic diamond is a diamond obtained by phase transformation of non-diamond carbon by ultra-high pressure or other artificial methods. Compared with natural diamond, it has the advantages of low production cost and good application effect. Due to the development of non-metallic materials and other hard and brittle materials, such as marble, granite, refractory, glass, ceramics, concrete, etc., the quality of diamonds for saw blades and drill bits is getting higher and higher, and the demand is increasing. The larger, more than 85% of the world's industrial diamonds have been replaced by synthetic diamond.
China's synthetic diamond industry started in the 1960s, about 10 years later in developed countries, but since the 1990s, the production of synthetic diamonds in domestic enterprises has begun to increase rapidly. According to industry association statistics, China's synthetic diamond production reached 2005. It is about 3.3 billion carats (1 carat = 0.2 g), accounting for about 70% of the global market. At present, there are more than 600 synthetic diamond production enterprises in the country, and the industry has entered a stage of rapid development. In 2005, China's synthetic diamond manufacturing industry value was 1.4 billion yuan, an increase of 16.84% over 2004. The industry profit was 450 million yuan, and the profit rate was 33.99%, an increase of 2.27 percentage points over the previous year. In the first half of 2006, the total output value of the synthetic diamond manufacturing industry was 720 million yuan, the industry revenue increased by 5.25%, the industry profit was 240 million yuan, the industry profit was 32.79%, which was 6.89 percentage points higher than the same period of 2005, and the industry sentiment was further improved.
While seeing the rapid development of the synthetic diamond industry, we should also pay attention to the fact that the artificial diamond products have low added value, and the high-end products mainly rely on imports. From the aspect of the varieties, according to the use of diamonds, the British Debeers has 44 brands. There are 25 brands in GE in the United States; there are only 11 brands in China, and there is no commercialized product in the most advanced DMD class. The number of grades is small and not fine, which affects the research and development of diamond products and the improvement of quality level. In addition, the vast majority of the domestic synthetic diamond market still uses single-particle compressive strength, that is, how many kilograms to price, and does not care about the brand.
In recent years, China's oil and natural gas exploitation has continued to be hot, especially the construction of large-scale engineering projects such as the exploitation of oil in the western development and the West-East Gas Transmission, which has a strong demand for diamond tools. According to the statistics of geological drilling tasks in recent years, hydropower, coal chemical and other statistical data, the market demand for diamond geological drills is estimated to be between 150,000 and 200,000, and the consumption of diamonds is about 3.5-4.5 million carats. With the continuous development of science and technology in the world, the era of artificial diamond industry monopolized by a few countries in the world has passed, and the production layout has developed toward multi-polarization. Asia will become a hot spot for the development of synthetic diamond industry in the early new century. Entering the 21st century building materials, geology, oil and gas, electromechanical, automotive and other industries will require a large amount of diamond. The demand for synthetic diamond market will be more vigorous and the prospects will be more brilliant.
