The use of earthy graphite?
As a conductive material: used for manufacturing the electrode, carbon nanotubes, carbon brush, and the positive electrode of the mercury rectifier in the electrical industry, graphite gasket, telephone parts, TV tube coating etc..
As refractory material: graphite and its products have the properties of high temperature resistance and high strength. They are mainly used in the metallurgical industry to make graphite crucibles. In the process of steelmaking, graphite is often used as a protective agent for steel ingots and lining of metallurgical furnaces.
The earthy graphite is the most common purpose there are three: one is mixed with a certain number of soil (the main component of silicon dioxide) pressed into the pencil core; the two is as part of a mechanical device or lubricant industry; three is a point solution, electroplating electrode or battery; in addition, it is also the artificial production of various other forms a shaped body (such as footballene, diamond, carbon nanotubes) of raw materials.
Wear resistant materials: graphite is often used as a lubricant in the mechanical industry. Lubricants can not be used in high speed, high temperature, high pressure conditions, and graphite wear-resistant materials can be at 200~2000 degrees Celsius temperature in a high sliding speed, without lubricating oil work. Many devices for conveying corrosive media are made of graphite materials, piston cups, seals and bearings. They do not need to be lubricated when running. Graphite is many metal processing (drawing, drawing) the good lubricant.
