Graphite powder for sale

Graphite powder is a finer form of graphite, a naturally occurring form of carbon in powdered form. The graphite has a unique structure consisting of stacked layers of carbon atoms held together by strong covalent bonds within each layer and weak van der Waals forces between layers. This structure gives it unique properties such as excellent lubricity, electrical conductivity, and thermal stability.

What is it made of?

Graphite powder is in the form of fine powder and its main component is carbon. Its raw materials are mainly divided into two types: natural and synthetic.

Natural graphite mainly comes from raw ore, which is made by mechanical grinding, chemical reduction and other methods.

Synthetic graphite is produced by screening and removing impurities. It is an inorganic non-metallic material with higher purity.

어떤 용도로 사용하나요?

Due to its high melting point and wear resistance, graphite powder is used as a lubricant for industrial machines without frequent replacement. It is also used to produce graphite-based products such as pencils and paints. In addition, it can be used to produce 그래핀는 반도체 등 다양한 용도로 사용되는 소재입니다, 탄소 섬유, 나노튜브, 복합 재료 등입니다.

It is also has another important use, which is as a carburizing agent for steelmaking. When used as a carburizing agent for eaf steelmaking, it is the debris cut off during the processing of artificial 흑연 전극. Because the carbon content of this kind of debris is as high as 99%.

In the process of EAF 제강, in order to ensure that the quality of the smelted product meets the standards, the carbon content in the molten steel needs to be adjusted. It plays a role in increasing carbon at this time, and due to the high carbon content (more than 90%), it is not only easily absorbed by the molten steel, but also greatly increases the dissolution speed of the molten steel.

사용 목적에 따라 입자 크기와 순도도 달라집니다. 제강 용광로에서 사용하는 경우 더 높은 순도 요구 사항이 필요합니다. 주로 S와 P의 함량에 대한 엄격한 요구 사항이 있습니다. S 함량은 0.2% 미만이어야 하고 P 함량은 0.02% 미만이어야 합니다.

What are its properties?

It is a non-metallic mineral material.  It has high electrical and thermal conductivity, extremely high melting point; good lubricity, plasticity and chemical stability, and is not corroded by acids, alkalis and organic solvents. Because of these properties, it is widely used in chemical industry, metallurgy, casting, lubrication, sealing and other industrial fields.
