- As conductive materials, graphite is widely used in the electrical industry as electrodes, brushes, carbon rods, carbon tubes, mercury rectifier cathode, graphite washers, telephone parts, TV picture tube coating and so on. The most widely used graphite electrodes, in the smelting of all kinds of alloy steel, Ferroalloy, the use of graphite electrodes, when the powerful current through the electrode into the furnace melting area, the generation of electric arc, so that electric energy into heat, temperature rise to 2000 ℃ or so, so as to achieve the melting or reaction. In addition, in the electrolytic metal magnesium , aluminum, and sodium, the anode of the electrolytic tank is also graphite electrode. The resistance furnace for producing carborundum is also used as conductive material for the furnace head with graphite electrodes. The graphite used in the electrical industry requires high granularity and grade.
- For wear-resisting and lubricating materials, graphite is often used as lubricant in the mechanical industry. Lubricating oils are often not available at high speeds, high temperatures, and under high pressure, while graphite-resistant materials can work at 1200 ℃ 2000 ℃ temperatures and at high sliding speeds (loom/s) without lubricating oil. Many of the equipment to transport corrosive media, widely used graphite materials made of piston rings, seals and bearings, they operate, do not need to add lubricating oil, graphite milk is also a lot of metal processing (wire drawing, tube) When the good lubricant.
Graphite is used extensively in industry, used for making smelting high-temperature crucible, mechanical industry lubricants, making electrodes and pencil cores; widely used in metallurgical industry, advanced refractory materials and coatings, military industrial fire material stabilizer, light industry pencil core, electrical industry carbon brushes, battery industry electrodes, chemical fertilizer industry catalysts. Flake graphite through deep processing, but also can produce graphite milk, graphite sealing materials and composite materials, graphite products, graphite antifriction additives and other High-tech products, as a major non-metallic mineral materials in various industrial sectors
