     The preparation of high purity graphite powder from graphite powder is to remove impurities in graphite powder and increase the carbon content of graphite powder to 99.9%.

This leads to the preparation of high purity graphite powder.

        1. Choose natural flake graphite from raw materials, and choose natural flake graphite with more than 80% carbon.Natural flake graphite is made into graphite powder by simple crushing. Water is added to the graphite powder and stirred.Mix into paste.

        2. Add strong oxidant and stir.

        3. Filtration, washing to neutral and drying
