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

Perhaps you've 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 unique nature. Isostatic Graphite is a good instance. In other words, graphite has special structure as a result it has its special function.

Firstly,graphite is with high temperature resistance. Generally 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 continues to be extremely little. What‘s more, its coefficient of thermal expansion is also very 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 become specific, graphite is with 1 hundred times greater conductivity than that of general nonmetal ore. As a matter of fact, it‘s thermal conductivity may be over that of steel, iron, lead and other metal materials. But around the other hand, its thermal conductivity decreases with the improve of temperature. Even in high temperature, graphite may be as insulator. Graphite can conduct electrical energy because every carbon atom in graphite forms three covalent bonds with other carbon atoms. What‘s more, each carbon atom still retains 1 free electrons to charge.

Thirdly, grahite is with great lubrication. To become particular, its lubrication performance depends on 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 the better the lubrication performance will probably be.

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

Now, let us discuss 1 application of graphite.

Graphite can be utilized as wear resistant lubricating material. Usually speaking, graphite, within the mechanical industry, is often utilized as lubricant. As all of us know, the lubricating oil can not be used within the condition of higher speed, high temperature and higher pressure. But in contrast, graphite‘s wear-resistant material may be used within 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 extensively used for making piston cup, sealing ring and bearings. That is simply because when they run, there is no have to add lubricant.
