99.99995% domestic ultra-high purity graphite products achieve new breakthroughs

Graphite is a material with excellent conductivity, thermal conductivity, chemical stability, and mechanical properties. It plays an indispensable role in various fields such as high-end manufacturing, energy industry, and scientific research, and is an important cornerstone for promoting technological progress and industrial development.

And these characteristics of graphite are also related to its purity. Simply put, the lower the impurity content of graphite, the higher its electrical and thermal conductivity, as well as its high temperature resistance and corrosion resistance. In addition, high-purity graphite has a higher density, a more uniform structure, and more outstanding mechanical properties. Therefore, graphite has a high demand for high purity in specific fields, especially in high-tech and precision industries.

There is a market standard for defining high-purity graphite - graphite with a carbon content of 99.99% or more is called ultra-high purity graphite. Ultra high purity graphite can better meet the application needs of high-tech fields such as new energy, new materials, aerospace, etc. Therefore, in today's constantly upgrading technology industry, the demand for ultra high purity graphite is also growing.

However, the production process of ultra-high purity graphite products is very complex. Previously, China was limited by high-temperature purification technology for graphite, and the purity of the products still had some defects compared to the international leading level. Under certain specific demands, the related raw materials still relied on imports. And recently, the graphite research team of China Minmetals Corporation's Minmetals Group has overcome relevant key technologies and broken this barrier.

It is reported that the research team focuses on the key common problems in the field of natural graphite and has independently developed and produced a continuous graphite purification process and equipment. Through a combination of physical and chemical purification, low-temperature and high-temperature continuous purification, ultra-high vacuum purification and other technologies, the team has successfully produced ultra-high purity graphite products with a purity of over 99.99995% and stable quality. More importantly, the entire process has significant control over production costs and is a process solution with obvious advantages.

We believe that this achievement will have a certain promoting effect on the research and development of carbon based materials such as high-end negative electrode materials, nuclear grade graphite, and semiconductor graphite, as well as related scientific research work involving high-purity graphite. It can further stimulate the development prospects of ultra-high purity graphite as a high-value material in China. We also look forward to the emergence of more mature purification technologies in the future, which will change our lives and enhance our international discourse power.
