Improving the electrical and thermal conductivity of graphite materials. After graphitization, the resistance of the product is significantly reduced, and the thermal conductivity is also significantly improved.

2.Improving the thermal and chemical stability of the material, such as oxidation resistance and corrosion resistance. And also reducing the coefficient of thermal expansion, etc.

3.Removing impurities. At the graphitization temperature (2200~2300℃), most of the impurities contained in the graphite material were vaporized and escaped. In general, graphitization can reduce ash by 70%. The high-purity graphite can be obtained by using chlorine gas for graphitization. 

4.Improving the wear resistance of graphite materials. The carbon of the random layer structure has the lubricity after transforming into graphite, and its wear resistance is improved significantly.

5.Reducing the hardness of graphite materials, so that graphite materials are easy to be used for precision machining. But graphitization also has some side effects. For example, the mechanical strength of the graphite material decreases, and the porosity increases.
