In the 2012 China Superhard Materials Technology Development Forum, Chairman Cao Qingzhong of Changge Huanghe Electric Co., Ltd. brought a technical report titled “Necessity of High Temperature and High Vacuum Purification of Diamond Synthesis Columns”.

The main contents of the technical report are summarized as follows: With the continuous development of diamond synthesis technology, the production technology of diamond synthesis column has gradually matured, and the post-treatment process has already attracted the attention of diamond manufacturers. In this paper, through the further understanding of synthetic diamond synthesis mechanism and analysis of high temperature and high vacuum purification treatment mechanism, the necessity of high temperature and high vacuum purification of diamond synthesis column is expounded, and the theoretical basis for stabilizing and improving diamond production quality is provided.

According to research and analysis, it is very necessary and best to use high temperature and high vacuum to purify diamond synthesis column. First, under the vacuum, the dehydration, degassing, and degreasing functions can be fully exerted; second, the metal reduction function can be fully exerted under vacuum; third, the metal evaporation function can be fully exerted under vacuum; fourth, the metal can be fully utilized under vacuum. Melting point reduction function. In short, the high temperature and high vacuum purification of diamond synthesis column process is an important technology in the diamond synthesis production process. With the continuous development of diamond technology, the production of diamond synthesis columns will have higher and higher requirements, and diamond workers need to work hard.
