As early as the late eighteenth century, diamonds were determined to be a crystal composed of carbon. Therefore, experimental research on the mystery of diamond crystal growth technology has been carried out. After nearly a hundred years of efforts, in the early 1950s, General Electric Company of the United States. The pursuit of using artificial diamonds on the high-pressure devices of 2.1×105MPa and 2000°C created by HTHall has become a reality, thus opening up a new era of diamond production and application. Therefore, it can be considered that the advent of synthetic diamond is a major achievement in the development of ultra-high pressure and high temperature technology. 
The ultra-high-pressure high-temperature device has evolved from a simple laboratory device to today's high-tech production-scale industrial device, and has undergone a process of practice, innovation, practice, and innovation. Recently, there are many types of devices that generate and maintain pressures of 4.0 to 6.0 GPa and temperatures above 2000 °C, but they are used in industrial production and are representative of: "Belt" type devices in Western countries, double-sided indentations of the former Soviet Union. The type of device and China's hinged six-sided anvil device, these ultra-high pressure and high-temperature devices have their own characteristics, which have made important contributions to the formation, development and growth of the superhard materials industry in their respective countries. From the long-term practice, we can realize the following several understandings: (1) Recognition: The large-scale high-pressure chamber is the only way to improve product quality, reduce production costs and obtain significant economic benefits. This problem can be seen from the data listed in Table 1. Get instructions. Table 1: The cost and price of a diamond factory over the years. As can be seen from Table 1, in the 20 years from 1963 to 1983, the cost per carat was reduced from the initial 4.39 US dollars to 0.18 US dollars. In the past ten years, due to the synthesis cavity Doubled, product costs fell by 22%. (1) Continuously improving King Kong's quality and granularity is a major goal of the superhard materials industry and an eternal subject of industry development. Among the many factors to achieve this goal, the large-scale high-pressure cavity is a key factor. This is confirmed by the data listed in Table 2. Table 2: Relationship between the size of the synthetic cavity and the quality of the product. (1) The main key technology - The main technical difficulty of the large-scale high-pressure mold is the enlargement of the carbide anvil (and the pressure cylinder). As early as the early 1970s, we proposed the large-scale problem of high-pressure chambers, and designed and manufactured 6×35MN, 6×50MN hinged six-sided anvil ultra-high pressure devices, which were installed in Shanghai Grinding Wheel Factory in 1971 and 1974 respectively. And Zhengzhou Abrasives Grinding Research Institute, because the large-diameter carbide anvil can not be provided, the device has not been put into operation for a long time, so that without the large-scale carbide anvil (cylinder), It is impossible to enlarge the UHV device.
