Production Process

 

 

Application

1. Refractory material:  Widely used in the metallurgical industry. 

2. Conducting material:   In the electronics industry, widely used for graphite electrode, brush,, etc 

3. Wear-resisting material and lubricant:  Use graphite as wear-resisting and lubrication materials, can be 100m/s speed sliding in - 200 ~ 2000 °C
                                                                  temperature range, no or less lubricanting oil. 

4. Sealing material: It can be as sealing ring in the equipment, such as centrifugal pump, hydraulic turbine ,etc. 

5. Anticorrosion material:  Widely used in petroleum, chemical, hydrometallurgy departments.  

6. Protection materials: Insulation, high temperature resistant, radiation  

7. Furnace parts:   resistance heating elements, induction susceptor, structural elements and charging plates, furnace linings, heat shields and covers for pulling monocrystalline silicon or optical fibers, etc. 

8. Anodes for the electrolysis of metals.

9. Parts for heat exchangers. 

Packaging & Shipping

The finished high-purity graphite is placed in a wooden box after packaged with moisture-proof paper or a plastic bag, and should be marked with "Fragile, Keep Dry".
