High Purity Crystalline Ultrafine Flake Graphite
Production
Description of Flake Graphite
The graphite crystals of natural flake graphite are scaly. They are transformed under high-intensity pressure and are divided into large-scale and fine-scale. It is one of the best flotation ore in nature, and high-grade graphite concentrate can be obtained through multiple grinding and selection. The floatability, lubricity and plasticity of this type of graphite are better than other types of graphite. Therefore, it has the greatest industrial value. The required pressure is usually greater than 1 gigapascal (75,000 psi), and the required temperature is usually greater than 750 degrees Celsius (1,380 F).
Since carbon deposits form natural flake graphite when they are under pressure and temperature, natural flake graphite powder is most commonly found in metamorphic rocks, and the deposits are fairly evenly distributed throughout the rock. Graphite has large flakes, large flakes, medium flakes and fine flakes.

Application of Flake Graphite
Natural Flake Graphite Powder is widely used in the fields of conductive coatings, glass manufacturing, lubricant formation, metallic alloys, nuclear reactors, powder metallurgy, and structural materials.
Natural flake graphite has found uses as the marking material ("lead") in common pencils, in zinc-carbon batteries, in electric motor brushes, and in various applications.
Aluminum/graphite composites for bearings, pistons, and liners in engines;
Carbon adsorbents for gas chromatography;
Cupper/graphite and silver/graphite nanocomposites for electrical brushes and contact strips;
Inorganic filler (graphite/polymer nanocomposites);
Support materials for precision metal powder catalysts Graphite/polymer nanocomposites for enhanced electrical conductivity;
Metal matrix composites for reduced friction.
Natural flake graphite powder is also used in vanadium redox batteries and nuclear reactors.
