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

Maybe you have seen Isostatic Graphite or Artificial Graphite. You think both of them are special and amazing. Then let us know much more about graphite.

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

Firstly,graphite is with high temperature resistance. Generally speaking, graphite‘s melting point may be as much as three thousand, nine hundred degrees. At the same time, its boiling point may be up to 4 thousand, two hundred and twenty 5 degrees. Even the ultra high temperature arc ignition, weight loss of graphite is still extremely little. What‘s 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 may be doubled.

Secondly, graphite is with the function of conductivity. To be specific, graphite is with one hundred occasions higher 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 high temperature, graphite can be as insulator. Graphite can conduct electricity simply because every carbon atom in graphite types 3 covalent bonds with other carbon atoms. What‘s more, each carbon atom nonetheless retains one free electrons to charge.

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

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

Now, let us talk about one application of graphite.

Graphite may be utilized as wear resistant lubricating material. Usually speaking, graphite, within the mechanical industry, is often used as lubricant. As all of us know, the lubricating oil can not be used in the situation of high speed, higher temperature and high pressure. 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 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's no have to add lubricant.
