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

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

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

Firstly,graphite is with high temperature resistance. Usually speaking, graphite‘s melting point may be as much as 3 thousand, nine hundred degrees. Simultaneously, its boiling point may be up to four thousand, two hundred and twenty five degrees. Even the ultra higher temperature arc ignition, weight reduction of graphite is still very little. What‘s much more, its coefficient of thermal expansion is also 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 may be doubled.

Secondly, graphite is with the feature of conductivity. To be particular, graphite is with one hundred times greater conductivity than that of general nonmetal ore. As a matter of fact, it‘s thermal conductivity can be over that of steel, iron, lead as well as other metal materials. But on the other hand, its thermal conductivity decreases using the improve of temperature. Even in high temperature, graphite may be as insulator. Graphite can conduct electricity simply because every carbon atom in graphite forms 3 covalent bonds with other carbon atoms. What‘s more, each carbon atom nonetheless retains 1 totally free electrons to charge.

Thirdly, grahite is with great lubrication. To become specific, its lubrication performance depends upon the size of graphite flake. In other words, the larger the flake or Graphite Block is, the smaller 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 great chemical stability at room temperature. As a result, it's with acid, alkali and corrosion resistance to organic solvents.

Now, let us talk about 1 application of graphite.

Graphite may be utilized as wear resistant lubricating material. Generally speaking, graphite, within the mechanical business, is frequently used as lubricant. As all of us know, the lubricating oil can not be utilized in the situation of higher speed, higher 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 widely used for creating piston cup, sealing ring and bearings. That's simply because once they run, there's no need to add lubricant.
