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

 Maybe you have seen Isostatic Graphite or Artificial Graphite. You think both 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 great example. In other words, graphite has special structure consequently it has its unique function.

Firstly,graphite is with higher temperature resistance. Usually speaking, graphite is melting point can be as much as 3 thousand, nine hundred degrees. At the same time, its boiling point can be as much as four thousand, two hundred and twenty 5 degrees. Even the ultra high temperature arc ignition, weight reduction of graphite is still very little. What is much more, its coefficient of thermal expansion can also be extremely small. In contrast, the graphite strength increases with the increasing temperature. By the way, when the temperature of graphite is two thousand, the graphite intensity may be doubled.

Secondly, graphite is with the feature of conductivity. To be particular, graphite is with 1 hundred occasions higher conductivity than that of general nonmetal ore. As a matter of fact, it is thermal conductivity may be more than that of steel, iron, lead as well as other metal materials. But around the other hand, its thermal conductivity decreases using the improve of temperature. Even in higher temperature, graphite can be as insulator. Graphite can conduct electrical energy because each carbon atom in graphite forms 3 covalent bonds with other carbon atoms. What is much more, each carbon atom still retains one free electrons to charge.

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

Fourthly, graphite is with great chemical stability. Graphite has good chemical stability at space 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 wear resistant lubricating material. Generally speaking, graphite, in the mechanical industry, is frequently utilized 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 is wear-resistant material may be utilized within 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 widely used for making piston cup, sealing ring and bearings. That is simply because when they run, there's no have to add lubricant.
