The use of high purity graphite in the field of industrial production has excellent performance. High purity graphite is used in conductive, lubrication, metallurgy, and other industrial production fields. High purity graphite production, from the beginning of the raw materials, should be strictly controlled the content of impurities, choose low ash raw materials, and in the production process to prevent the increase of pollutants as far as possible. However, the reduction of contaminants to the degree required is primarily in the graphite chemical sequence. Graphitization occurs at high temperatures, where the oxides of many impurity elements will decompose and evaporate. The higher the graphitization temperature is, the more impurities are discharged, the higher the purity of the high purity graphite products are produced. The high purity graphite is used to make use of its excellent conductivity, lubrication, high-temperature resistance, etc.
