Why Is Graphite So Unique And Practical In Our Every day Life?

Perhaps you have seen Isostatic Graphite or Artificial Graphite. You think both of them are special and incredible. Then let us know much more about graphite.

As a few of us know, graphite is with its special nature. Isostatic Graphite is really a good instance. In other words, graphite has unique structure as a result it has its unique function.

Firstly,graphite is with higher temperature resistance. Usually speaking, graphite‘s melting point can be up to three thousand, nine hundred degrees. Simultaneously, its boiling point can be as much as four thousand, two hundred and twenty 5 degrees. Even the ultra higher temperature arc ignition, weight loss of graphite continues to be extremely small. What‘s more, its coefficient of thermal expansion can also be extremely little. In contrast, the graphite strength increases with the increasing temperature. By the way, when the temperature of graphite is two thousand, the graphite intensity can be doubled.

Secondly, graphite is with the function of conductivity. To become particular, graphite is with 1 hundred times greater conductivity than that of common nonmetal ore. As a matter of fact, it‘s thermal conductivity can be over that of steel, iron, lead and other metal supplies. But on the other hand, its thermal conductivity decreases with the increase of temperature. Even in higher temperature, graphite can be as insulator. Graphite can conduct electrical energy simply because every carbon atom in graphite types 3 covalent bonds with other carbon atoms. What‘s much more, every carbon atom still retains one totally free electrons to charge.

Thirdly, grahite is with good lubrication. To be specific, its lubrication overall performance depends upon the size of graphite flake. In other words, the bigger the flake or Graphite Block is, the smaller sized the friction coefficient will be, and the much better the lubrication overall performance will probably be.

Fourthly, graphite is with great chemical stability. Graphite has good chemical stability at space temperature. As a result, it's with acid, alkali and corrosion resistance to organic solvents.

Now, let us talk about one application of graphite.

Graphite may be utilized as wear resistant lubricating material. Usually speaking, graphite, within the mechanical industry, is often used as lubricant. As all of us know, the lubricating oil can not be utilized within the situation of higher speed, high temperature and high pressure. But in contrast, graphite‘s wear-resistant material may be utilized in the temperature of two hundred to two thousand degrees and with out lubricating oil.

As for a lot of devices that transport the corrosive medium, Graphite Heater is extensively used for creating piston cup, sealing ring and bearings. That is simply because once they run, there is no need to add lubricant.
