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

Perhaps you have noticed Isostatic Graphite or Artificial Graphite. You think both of them are unique and amazing. Then let us know much more about graphite.

As some of us know, graphite is with its unique nature. Isostatic Graphite is really a great example. In other words, graphite has unique structure consequently it has its special function.

Firstly,graphite is with high temperature resistance. Usually speaking, graphite‘s melting point can be as much as 3 thousand, nine hundred degrees. Simultaneously, its boiling point can be up to four thousand, two hundred and twenty 5 degrees. Even the ultra higher temperature arc ignition, weight reduction of graphite is still extremely little. What‘s more, its coefficient of thermal expansion is also very little. In contrast, the graphite strength increases using the growing 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 general nonmetal ore. As a matter of reality, it‘s thermal conductivity can be over that of steel, iron, lead and other metal materials. But on the other hand, its thermal conductivity decreases with the improve of temperature. Even in higher temperature, graphite can be as insulator. Graphite can conduct electricity simply because every carbon atom in graphite forms 3 covalent bonds with other carbon atoms. What‘s more, every carbon atom nonetheless retains 1 totally free electrons to charge.

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

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

Now, let us talk about one application of graphite.

Graphite can be utilized as wear resistant lubricating material. Generally speaking, graphite, in the mechanical industry, is often used as lubricant. As all of us know, the lubricating oil can not be used within the condition of higher speed, high temperature and higher 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 many devices that transport the corrosive medium, Graphite Heater is widely utilized for creating piston cup, sealing ring and bearings. That is because once they run, there is no have to add lubricant.
