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.

After intensive processing flake graphite can be made into graphite oil, which can then be used in lubricants and mold release agents as well as wire drawing agents and conductive coatings. It can also produce expanded graphite which is used in flexible graphite products like flexible graphite seals, flexible graphite-composite products, 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 such 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 graphite flake materials. 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, it is necessary to improve graphite's conductivity and reduce the amount graphite flakes that are added.

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. This allows for the preparation of composite conductive fillers. They are used in conductive coateds in an amount 30%. This not only improves conductivity, but also provides corrosion resistance.

What is Natural Graphite? This is naturally formed graphite.
Natural graphite is a valuable industrial mineral. It has many uses in nearly every aspect of manufacturing including electronics, atomic energie, hot metal processing and friction, coatings and aerospace.

What is graphite, exactly?
Graphite is a crystalline form the element carbon. It is composed of layers of graphene that are stacked. Graphite is a naturally occurring carbon and the most stable under standard conditions.
Natural and synthetic graphite are used extensively in pencils and lubricants. It turns to diamonds at high temperatures and pressure. It is a weak conductor for heat and electricity.

What types of graphite are there?
Natural graphite can be found in a variety of deposits.
If not fractured, tiny flakes or flake graphite of crystalline graphite are found as flat, flat, and plate-like particles. Edges can become irregular or angular if damaged.
Amorphous graphite. This is a very fine flake graphite that's sometimes called amorphous.
Lumpy graphite or veined Graphite is found in fissures and cracks as lumpy plate symbionts. These crystalline aggregates are fibrous or needle-like, likely of hydrothermal origin.
Highly ordered pyrolytic Graphite refers graphite whose angle distribution between graphite sheet is less than 1deg
The term "graphite fiber" is sometimes used to refer to carbon fiber or carbon-fiber-reinforced polymers.

What can natural graphite be used for?
Natural graphite, which has a melting temperature of up to 3650, is a refractory mineral and a good conductor and heat conductor. Graphite can be used for batteries, lubricants or refractories.

Anode for an electric vehicle
Graphite, the fundamental element of the production process for lithium-ion batteries, is at the moment the only one. The demand for high-quality battery-grade graphite for the anode is rapidly growing and will continue to grow exponentially through 2022. These batteries are mostly used in consumer electronics and electric vehicles.
Graphite is a valuable raw material for light materials such as carbon fibre and reinforced plastics that are used in cars or aircraft parts.

Lubricants & Grease
Graphite has become a very important dry solid lubricant. It can be used for steel, titanium, stainless, special superalloy stamping pieces, die forging and hot extrusion.
Graphite exhibits excellent lubrication and demolding properties. It has excellent tool wetability and concealment power. The combination of graphite that is very pure and refined oil results in reduced engraving and tool wear.

Refractory metals for steel, the crucible etc.
Graphite has a conductivity that is 100 times greater than ordinary non-metallic mineral minerals. Graphite is used to protect ingots and as a lining in metallurgical furnaces.

Graphite is also used as an alloy component in the aluminum and semiconductor industries.
Graphite is available in two forms: thin sheets and expanded graphite. This allows for the creation of metal-graphite compounds. Graphite can be used in a variety of ways depending on its direction and amount. It can be used for thermal management, passive damping elements in factories, mechanical engineering, and bearing materials for slow-rotating plain bearings. You can tailor the properties of materials such as thermal conductivity, strength, damping coefficient and thermal expansion coefficient to your intended use by combining them. Powder metallurgy can control carbide content, and can achieve up 90% of the volume graphite without pores. Even high graphite levels can be mechanically finished.

Brake plates
Brake pads are made of graphite. Graphite is used in brake pads.

Pencil
The production of pencils from graphite is a long-standing tradition. Since the 19th Century, pencil leads were fired from a mixture graphite-clay. The pencils are hardened and colored by clay, and then glazed with graphite to give them a black-colored and soft texture.

Natural graphite prices
Price is affected by many factors, including supply and demand, market trends, economic activity and unexpected events.
