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

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

As some of us know, graphite is with its special nature. Isostatic Graphite is a great instance. 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 can be up to 3 thousand, nine hundred degrees. Simultaneously, its boiling point may be as much as 4 thousand, two hundred and twenty five degrees. Even the ultra high temperature arc ignition, weight reduction of graphite continues to be very little. What‘s much more, its coefficient of thermal expansion is also very small. In contrast, the graphite strength increases with 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 greater conductivity than that of common nonmetal ore. As a matter of reality, it‘s thermal conductivity can be more than 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 high temperature, graphite can 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 nonetheless retains 1 free electrons to charge.

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

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

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

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