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

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

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

Firstly,graphite is with high temperature resistance. Usually speaking, graphite?¡¥s melting point can be up to 3 thousand, nine hundred degrees. At the same time, its boiling point can be as much as four thousand, two hundred and twenty five degrees. Even the ultra higher temperature arc ignition, weight reduction of graphite continues to be very small. What?¡¥s much more, its coefficient of thermal expansion can also be 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 function of conductivity. To be particular, graphite is with 1 hundred occasions greater conductivity than that of general nonmetal ore. As a matter of reality, it?¡¥s thermal conductivity can be more than that of steel, iron, lead and other metal materials. But on the other hand, its thermal conductivity decreases with the increase of temperature. Even in higher temperature, graphite may be as insulator. Graphite can conduct electrical energy because each carbon atom in graphite types three covalent bonds with other carbon atoms. What?¡¥s much more, each carbon atom still retains one 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 bigger the flake or Graphite Block is, the smaller the friction coefficient will probably be, and also the much better the lubrication performance will be.

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

Now, let us talk about 1 application of graphite.

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

As for many devices that transport the corrosive medium, graphite is widely utilized for making piston cup, sealing ring and bearings. That's simply because when they run, there's no need to add lubricant.
