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

 Maybe you've noticed Isostatic Graphite or Artificial Graphite. You believe each of them are special and amazing. Then let us know more about graphite.

As some of us know, graphite is with its special nature. Photovoltaic Graphite is a good example. In other words, graphite has special structure as a result it has its unique function.

Firstly,graphite is with higher temperature resistance. Usually speaking, graphite?¡¥s melting point may be up to 3 thousand, nine hundred degrees. Simultaneously, its boiling point can be as much as four thousand, two hundred and twenty five degrees. Even the ultra high temperature arc ignition, weight loss of graphite is still extremely little. What?¡¥s much more, its coefficient of thermal expansion is also extremely 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 using the function of conductivity. To become particular, graphite is with 1 hundred occasions greater conductivity than that of general nonmetal ore. As a matter of reality, it?¡¥s thermal conductivity may be over that of steel, iron, lead as well as other metal materials. But on the other hand, its thermal conductivity decreases using the increase of temperature. Even in higher temperature, graphite may be as insulator. Graphite can conduct electrical energy simply because every carbon atom in graphite types three covalent bonds with other carbon atoms. What?¡¥s much more, every carbon atom still retains 1 free electrons to charge.

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

Fourthly, graphite is with good 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 discuss 1 application of graphite.

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