Because of its special structure, graphite has special properties of lubrication, and it is often used as a wear-resistant lubricant in the machinery industry.

Graphite is a kind of allotrope of carbon, gray black, opaque solid, chemical stability, corrosion resistance, with acid, alkali and other agents are not easy to react. Natural graphite from graphite deposits, can also be petroleum coke, asphalt coke as raw materials, after a series of processes to make artificial graphite. Graphite is burned in oxygen to produce carbon dioxide, which can be oxidized by strong oxidants such as concentrated nitric acid and potassium permanganate. It can be used as an antiwear agent and lubricant. High purity graphite can be used as a neutron reducer in atomic reactors. It can also be used in the manufacture of crucible, electrode, brush, dry battery, graphite fiber, heat exchanger, cooler, arc furnace, arc lamp, pencil lead and so on.

Because of its special structure, graphite has the following special properties:

(1) High temperature resistance

The melting point of graphite is 3850±50℃. Even if it is burned by ultra-high temperature arc, the weight loss is small and the coefficient of thermal expansion is small. The strength of graphite increases with the increase of temperature. At 2000℃, the strength of graphite doubles.

(2) electrical and thermal conductivity

The conductivity of graphite is one hundred times higher than that of ordinary non-metallic ore. The thermal conductivity is higher than steel, iron, lead and other metal materials. The thermal conductivity decreases with increasing temperature, even at extremely high temperatures, graphite becomes an adiabatic.

(3) lubricity

The lubrication performance of graphite depends on the size of the graphite flake. The larger the flake, the smaller the friction coefficient and the better the lubrication performance.

(4) Plasticity

Graphite has good toughness and can be ground into very thin sheets.

Henan LG Graphite Co.,Ltd., headquartered in Zhengzhou City, Henan Province, is a comprehensive enterprise integrating graphite product development, production, import and export sales and after-sales service. The company produces isostatic graphite, high purity molded graphite, EDM graphite and other graphite raw materials. Liugong graphite firmly believe that quality is the survival of the quality is the means of competition, we never slack quality control.
