The powder is obtained by grinding manually or mechanically, or as a result of the decomposition of coke.
The graphite powder has a gray-black color with a metallic sheen. Powder particles are in the form of flakes. It has a soft, layered structure. Well pressed and stamped.
Conducts well heat and electric current, has the properties of a magnetic.
It is a refractory low elastic material.
Pressed graphite powder is the basis for the production of rods for pencils, as well as graphite rods of large diameter for the needs of the atomic, electrical, instrument-making industries. Used in printing, automotive, electronics.
Due to its layered structure, it is a component of graphite grease. As a filler it is used in the foundry and metallurgical industry (powder metallurgy), in the production of power batteries.

There are 3 main types of graphite powder: GII –A, GII –B and GII-C
Graphite grade A is characterized by moisture and ash content <1%, carbon content> 99% and sulfur <0.05%. Graphite grade B has ash content <10%, carbon content> 98% and sulfur <0.5%, humidity <5%. For grade C, the ash content is <22%, carbon> 80%, humidity <5%, sulfur <1.5%. Other characteristics of the three grades are identical.
The density of the powder is not lower than 0.85 g / cm3,
The grain size in graphite powder can vary from 0.1 mm to 5 mm;
