About High Purity Graphite Powder Flake Graphite C Powder:
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, graphite 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. The graphite powder price is much cheaper.
Depending on the application, the purity and/or size of natural flake graphite may be more important. The spherical industry requires large-size and flake graphite, while the refractory industry mainly focuses on the flake size.

How is High Purity Graphite Powder Flake Graphite C Powder produced?
The high purity and high carbon natural flake graphite powder CAS 7782-42-5 is prepared by laser ablation method.
Natural flake graphite is formed when carbon material is subjected to high pressure and high temperature. The carbon source material can be either organic or inorganic, although most commercially sourced flake graphite comes from organic deposits.

Application of High Purity Graphite Powder Flake Graphite C Powder
Natural Flake Graphite is widely used in the fields of conductive coatings, glass manufacturing, lubricant formation, metallic alloys, nuclear reactors, powder metallurgy, and structural materials.
Natural 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;
Graphite powder for locks;
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.
Flake graphite is also used in vanadium redox batteries and nuclear reactors. Vanadium redox batteries use the chemical properties of
vanadium and graphite to reliably store excess energy for a long time. Nuclear reactors wrap uranium in large graphite spheres.
Storage Condition of High Purity Graphite Powder Flake Graphite C Powder :
The damp reunion will affect C powder dispersion performance and using effects, therefore, natural flake graphite C powder should be sealed in vacuum packing and stored in cool and dry room, the natural flake graphite C powder can not be exposure to air. In addition, the C powder should be avoided under stress.
Packing & Shipping of High Purity Graphite Powder Flake Graphite C Powder :
We have many different kinds of packing that depend on the natural flake graphite C powder quantity.
Natural flake graphite C powder packing: vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.
Natural flake graphite C powder shipping: could be shipped out by sea, by air, by express as soon as possible once payment receipt.
