Graphite powder

Graphite powder

Graphite powder is an important carbonaceous material

It is a black solid particle made of natural flake graphite by mechanical processing. Its chemical composition is mainly c, si and other elements, and contains a small amount of s, p, fe, mn and other impurities. High-purity graphite powder has the advantages of high temperature resistance (3000°C), corrosion resistance (insoluble in acid) and lubricity.

Graphite powder is one of the important raw materials for the production of pencil lead; it is also a raw material for making refractory materials and coatings; it is also an important carbonaceous material, which is widely used in the metallurgical industry as a deoxidizer for steelmaking and for the manufacture of artificial diamond and refractory materials, etc.; In addition, it is also used as an additive for paint fillers and abrasives.

Graphite powder is widely used and used in a large amount as a grinding medium, used for the friction of bearings of precision instruments and sliders in clock winding devices, etc. Due to graphite's good thermal and electrical conductivity and high hardness characteristics It is widely used in the electronics industry as electrode paste and various resistors. In addition, it is also widely used in the aerospace field.

In the chemical industry, it is mainly used to purify metals or alloys and to prepare strong corrosive substances such as hydrofluoric acid as a protective gas. In the machinery industry, it is widely used in the production of seals for automotive engine components.
