Why Is Graphite So Unique And Practical In Our Daily Life?

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

As a few of us know, graphite is with its special nature. Photovoltaic Graphite is a good instance. In other words, graphite has unique structure consequently it has its unique feature.

Firstly,graphite is with higher temperature resistance. Generally speaking, graphite?¡¥s melting point can be as much as three thousand, nine hundred degrees. At the same time, its boiling point may be as much as 4 thousand, two hundred and twenty five degrees. Even the ultra higher temperature arc ignition, weight loss of graphite continues to be extremely little. What?¡¥s more, its coefficient of thermal expansion is also very small. 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 feature of conductivity. To be specific, graphite is with one hundred occasions higher conductivity than that of common nonmetal ore. As a matter of fact, it?¡¥s thermal conductivity may be over that of steel, iron, lead and other metal materials. But around 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 because every carbon atom in graphite types three covalent bonds with other carbon atoms. What?¡¥s more, each carbon atom nonetheless retains 1 free electrons to charge.

Thirdly, grahite is with great lubrication. To become particular, its lubrication overall performance depends on the size of graphite flake. In other words, the larger the flake or Graphite Block is, the smaller sized the friction coefficient will probably 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's with acid, alkali and corrosion resistance to organic solvents.

Now, let us discuss one application of graphite.

Graphite can be used as wear resistant lubricating material. Generally speaking, graphite, in the mechanical industry, is frequently used as lubricant. As all of us know, the lubricating oil can not be used within the situation of higher speed, higher temperature and high stress. But in contrast, graphite?¡¥s wear-resistant material may be used 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 is widely utilized for making piston cup, sealing ring and bearings. That is simply because once they run, there is no have to add lubricant.
