Graphite Particle
Graphite powderis a non-metallic mineral material. Graphite powder has high conductivity and thermal conductivity, high melting point, good lubricity, plasticity and chemical stability. Graphite powder can be corroded by acid, alkali and organic solvents. Therefore, it is widely used in chemical, petroleum, metallurgy, casting, lubrication, sealing and other industrial fields.

Graphite Particle
Graphite particles are also called graphite columns, also known as small-size graphite rods. They are called in different ways due to different industries, but their products are the same and need to be processed from high-purity lubricated and conductive graphite raw material. Graphite particles have a wide range of uses. They can be used as lubricating particles of copper guide sleeves, self-lubricating bearing, and carburizing agents.
Advantages of adding graphite powder in steel smelting
Because of the excellent performance of graphite powder carburize, it has become an indispensable auxiliary additive for the production of high-quality steel in the ironmaking industry. The following are the benefits of adding graphite powder in steel smelting:
- Graphite powder carburizing agent has the characteristics of high fixed carbon content, heat resistance, smooth moistening performance, and easy absorption. It is added to the surface of molten iron according to a certain proportion. According to the vortex mixing of mechanical equipment or manual service mixing, it can digest and absorb the appropriate carbon in graphite powder carburizing agent, reduce sulfur and other residual components in steel, improve the quality of steel and reduce the cost of casting products, Improve economic efficiency.
Application of graphite powder in coating industry
Graphite powder is widely used as coatings in the industry. Many coatings can change the properties of coatings by adding graphite powder.
As an anticorrosive material, the antirust primer made of carbon black, talc powder, and oil has good chemical and solvent corrosion resistance; If zinc yellow and other chemical pigments are added into the formula, the antirust effect is better. And has a strong corrosion resistance!
Expandable graphite is a kind of graphite intercalation compound obtained by chemical or electrochemical treatment with natural graphite flakes as raw materials. Under the condition of the heating, the volume of expandable graphite expands rapidly (up to 300 times) to suffocate the flame. At the same time, it forms expansions, which can isolate the flame and delay or interrupt the flame spread. Moreover, it is nonflammable, has good softness, high surface energy, and good strength of the carbonized layer. But the volume and dosage of the expansion body should be selected appropriately.
Graphite powder is black, it is very similar to iron powder in appearance, it is difficult to distinguish the two.
Graphite powder and iron powder can be distinguished by physical and chemical methods.
Physical methods distinguish graphite powder from iron powder.
Graphite powder and iron powder can be distinguished by chemical methods.
To sum up, it is the difference between graphite powder and iron powder.
