Why graphite can be used as conductive material?
Lubricants can not be used in high speed, high temperature, high pressure conditions, and graphite wear-resistant materials can be at the temperature and at a high sliding speed, without lubricating oil work. Many transporting corrosive media devices are widely used, which is made of graphite material piston ring, the sealing ring and the bearing, they are running, without adding lubricating oil, graphite and many metal processing when good lubricant.
Graphite used in the electrical industry requires a high degree of particle size and grade. Such as alkaline batteries and some special electric carbon products, requiring graphite particle size control within the scope of the project, grade above, harmful impurities are required in the following. The graphite used in a picture tube for television is required below. As a wear-resistant and lubricating material, graphite is often used as a lubricant in the mechanical industry.
Widely used as electrode, graphite, carbon brush, carbon nanotubes, mercury rectifier cathode, graphite gasket, telephone parts, TV tube coating and so on in the electrical industry. The most widely used in the smelting of graphite electrode, alloy steel, iron alloy, graphite electrode, the strong current through the melting zone, the arc electrode into the electric furnace, the electrical energy into heat, the temperature rises to around, so as to achieve the purpose of melting or reaction. In addition, in the electrolysis of metal, magnesium, aluminum and sodium, the anode of the electrolytic cell is also made of graphite electrode. The resistance furnace used for the production of rigid sand is also made of graphite electrode as the conducting material of the furnace head.
