Natural flake graphite Natural crystalline graphite has a shape similar to fish phosphorus. It belongs to the hexagonal system and has layers. It exhibits good resistance to heat, electrical conductivity, heat conduction and lubrication.
Flake graphite can be found in complete crystals or thin flakes. It has good physical and chemical properties and excellent thermal conductivity.

Natural Flake Graphite Application

Refractory
Flake graphite is used widely in advanced refractories in the metalurgical industry. Magnesia carbon bricks, crucibles and others. Stabilizers in the military industry for pyrotechnics, desulfurization accelerators, pencil leads, and carbon brushes for industry.

Graphite Emulsion can be made from flake graphite after it has been processed. It can be used in lubricants and mold release agents, wire-drawing agents, conductive coatings, and other applications. Expanded graphite is also possible. This raw material can be used in flexible graphite products like flexible graphite seals, flexible graphite composites, and so on.

Coating
Flake graphite is used primarily as a functional filler for coatings.

Anti-corrosion material: The anti-rust primer is made of natural phosphorous flake Graphite and carbon Black, talcum Powder, and oil. It has good resistance to chemicals and solvents. Chemical pigments like zinc yellow can be added to the formulation to prevent rust.
Expandable graphite can be used as a fireproof material. This is a form of graphite interlaminar compound that has been produced by electrochemical or chemical treatment of natural graphiteflakes. Expandable graphite expands rapidly under heating (up to 300x), which suffocates a flame. It also generates expansions which can help isolate the flame or stop it from spreading. It is incombustible, flexible, strong, and has high surface energie.

Flake graphite may be used to make conductive coatings or as a carbon-based filler. Due to the large number of graphite flake added, the coating’s performance and ease of application will be reduced. Therefore, we take measures to increase the conductivity of graphite as well as reduce the amount added graphite flakes.

This short-cut fiber material is a solvent-free thick films conductive coating with functional filleders. It has characteristics such as anti-corrosive medium penetration and low curing residue stress. It is also resistant to matrix deformation and cracking. The coating can be used for long-term static electricity transmission. The inner wall of crude oil storage tank’s crude oil storage tanks can be coated with natural phosphorous flake graphite.
According to reports, electroless plating technology can be used to coat graphite dust with metals like nickel, silver, and copper. These fillers are used in conductive coated in an amount of 30 percent. It not only has good conductivity but also provides corrosion resistance.
