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

Perhaps you have noticed Isostatic Graphite or Artificial Graphite. You believe both of them are unique and amazing. Then let us know more about graphite.

As some of us know, graphite is with its unique nature. Isostatic 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 can be as much as three thousand, nine hundred degrees. At the same time, its boiling point may be as much as 4 thousand, two hundred and twenty 5 degrees. Even the ultra higher temperature arc ignition, weight loss of graphite is still extremely small. What‘s more, its coefficient of thermal expansion can also be very little. 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 particular, graphite is with one hundred times 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 may be as insulator. Graphite can conduct electrical energy simply because every carbon atom in graphite forms three covalent bonds with other carbon atoms. What‘s more, each carbon atom nonetheless retains one totally free electrons to charge.

Thirdly, grahite is with good lubrication. To be specific, its lubrication 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 the better the lubrication performance will probably be.

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

Now, let us discuss 1 application of graphite.

Graphite may be utilized as wear resistant lubricating material. Usually speaking, graphite, within the mechanical business, is frequently used as lubricant. As all of us know, the lubricating oil can not be used within the situation of higher speed, high temperature and high pressure. 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 a lot of devices that transport the corrosive medium, Graphite Heater is extensively utilized for creating piston cup, sealing ring and bearings. That is simply because once they run, there is no have to add lubricant.
