In a significant advancement for high-tech industries, the Chinese mainland has achieved a groundbreaking milestone in graphite purification. A research team from China Minmetals Corporation, under the leadership of Wang Jionghui, has developed a new process that elevates graphite purity from 95% to an impressive 99.99995%.
This ultra-pure graphite is essential for manufacturing materials used in cutting-edge machinery and equipment. The collaborative efforts between Wang's team and several equipment manufacturing enterprises have refined this purification technology, ensuring consistent high-quality output.
China Minmetals Corporation, leveraging its substantial graphite reserves in Hegang City, Heilongjiang Province, operates a processing plant with an annual capacity of 200,000 tonnes. The company is also pioneering the creation of ultra-pure graphite products, including high-end negative electrode materials and carbon-based semiconductor graphite, positioning itself at the forefront of the high-tech materials market.
Graphite's exceptional properties—such as electrical conductivity, lubrication, and resistance to erosion and high temperatures—make it a cornerstone mineral for the development of advanced technologies. This breakthrough not only reinforces China's role in the global graphite market but also paves the way for innovations in various high-tech sectors.
