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

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

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

Firstly,graphite is with higher temperature resistance. Usually speaking, graphite?¡¥s melting point may be up to three thousand, nine hundred degrees. At the same time, its boiling point may be up to four thousand, two hundred and twenty five degrees. Even the ultra high temperature arc ignition, weight loss of graphite is still very little. What?¡¥s much 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 feature of conductivity. To become specific, graphite is with 1 hundred occasions greater conductivity than that of common nonmetal ore. As a matter of fact, it?¡¥s thermal conductivity may be more than that of steel, iron, lead as well as other metal supplies. But around the other hand, its thermal conductivity decreases with the increase of temperature. Even in high temperature, graphite can be as insulator. Graphite can conduct electricity because each carbon atom in graphite forms 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 particular, its lubrication performance depends upon the size of graphite flake. In other words, the larger the flake or Graphite Block is, the smaller the friction coefficient will probably be, and the better the lubrication overall performance will probably be.

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

Now, let us talk about one application of graphite.

Graphite can be used as put on resistant lubricating material. Generally speaking, graphite, within the mechanical industry, is frequently utilized as lubricant. As all of us know, the lubricating oil can not be used in the situation of higher speed, high temperature and higher stress. But in contrast, graphite?¡¥s wear-resistant material may be utilized in the temperature of two hundred to two thousand degrees and without lubricating oil.

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