1. Sealing materials: Mix the raw material high -carbon graphite with concentrated sulfuric acid and concentrated nitric acid for acidification, and then suppress the molding after heat treatment. The prepared flexible graphite is a new type of high -performance sealing material. Compared with traditional sealing materials such as asbestos rubber, it has good performance of compression, reflection, elasticity, self -adhesion, low density, etc., and can be used for a long time under high temperature and high corruption. The graphite board and sealing elements made are widely used in industries such as Aerospace, Machinery, Electronics, Nuclear Energy, Petrochemical, Power, Ship, Small, and other industries. The excellent characteristics of lubrication, plasticity and chemical stability are known as the "king of sealing" in the world.

2. The field of environmental protection: The expansion graphite obtained by high temperature puffing has a rich hole structure, so it has excellent adsorption performance, so it is widely used in environmental protection and biomedicine. There are two types of pores that can expand graphite. The hole accumulation accounts for about 98 %, and is mainly a large hole. The distribution range of the pore diameter is 1 to 10.3 nm. Since it is mainly large pores and medium holes, it is different from the adsorption characteristics such as activated carbon materials in terms of adsorption characteristics. It is suitable for liquid -phase adsorption, not the absorbing gas. It is hydrophobic during liquid -phase adsorption. 1 G can expand graphite can adsorb more than 80 g heavy oil. Therefore, it is an environmentally friendly material with promising water pollution. Microbial (bacteria) treatment is often used in chemical enterprises' wastewater treatment. Can expand graphite is a good microbial carrier, especially in the water treatment of oil -based organic macromolecular pollution. Due to good chemical stability and renewable renewal, there is a good application prospect.

3. Medicine: Because the expansion of graphite has the adsorption characteristics of organic and biomantic molecules, it has a wide range of application prospects in biomedical materials.

4. High -energy battery material: Expansion graphite as a battery material is the use of freedom to use the expansion graphite layer to change into electrical energy. Usually use expansion graphite as cathode, lithium anode, or expansion graphite composite silver oxide. The cathode, zinc is anode. The expansion graphite of metal halide, such as fluorine, graphite, and AUCL3 and TIF4 has been applied to the battery.
