The preparation process of high-purity graphite is briefly as follows: first, water is added to natural graphite to make it paste. In addition, strong oxidant is added and heated and stirred. Finally, filter, wash to neutral and dry.

The liquid phase method is simple to produce high-purity graphite and has no strict requirements on raw materials. It is suitable for processing raw materials with 10000 mesh to 20 mesh and fixed carbon of more than 80%.

Through this process, high-purity natural flake graphite with a purity of 99.9% – 99.998% can be obtained, which can meet the needs of atomic energy and aerospace industry, with low cost and stable quality.
