What is the application of flake graphite?
Scale graphite is a natural graphite ore with a shape similar to fish scales, which is a hexagonal crystal with a layered structure. It has good acid and alkali resistance, high temperature resistance, electrical conductivity, thermal conductivity, and lubrication properties.
1. What is flake graphite used for?
Flake graphite is a kind of natural crystalline graphite. After mining and purification of graphite minerals, the general shape is fish scales, which is called flake graphite. Natural flake graphite has complete flake crystals, thin and good toughness, and stable physical and chemical properties.
The density of flake graphite is generally 1.9 g/cm3, the reference range is the density of graphite: 2.09 to 2.33g/cm³.
Graphite flakes are generally processed into powder. There are many specifications of graphite flakes, such as 50 mesh, 80 mesh, 100 mesh, 200 mesh, 325 mesh, 800 mesh, etc. The larger the mesh number of the flake graphite powder, the smaller the particle size of the flake graphite powder. The flake graphite powder is a natural flake graphite product. The larger the particle size of the flake graphite powder during the initial crushing process, the better the flake graphite characteristics. Obviously, it can be seen that it has a scaly lamellar structure and metallic luster.
What is the melting point of flake graphite?
The melting point of flake graphite is between 3652°C-3697°C.
National standard for flake graphite?
The national standard implemented by flake graphite is "flake graphite GB/T 3518-2008"
The price of flake graphite: The price of flake graphite varies according to the carbon content and quality, generally between 3000-20000 yuan / ton.
2. the use of flake graphite
Flake graphite is widely used in refractory materials and coatings in the smelting industry. Such as magnesia carbon bricks, crucibles, etc. Stabilizers for military pyrotechnics, desulfurization accelerators in smelting industry, pencil leads, carbon brushes in electrical industry, electrodes in batteries, catalysts in chemical industry, etc. The flake graphite is deeply processed and can be used to produce graphite milk, which is used in lubricants, mold release agents, wire drawing agents, conductive coatings, etc. Expanded graphite can also be produced as a raw material for flexible graphite products, such as flexible graphite seals and flexible graphite composite products.
3. The difference between flake graphite and graphite powder
Flake graphite means that the graphite molecules are arranged in layers to form a lamellar structure, while the graphite powder is a spherical structure composed of graphite molecules, and the size is in the unit of mesh. Natural flake graphite is a flake graphite powder product after deep processing such as ore mining, flotation, drying, sorting, purification, and crushing. Artificial graphite powder is a product of petroleum coke graphitization. Natural flake graphite is flaky in the microscopic state.
The difference between flake graphite and expanded graphite
Expanded graphite is a deep-processed product of flake graphite. Expanded graphite (Expanded Graphite) is a loose and porous worm-like substance obtained from natural graphite flakes through intercalation, water washing, drying and high temperature expansion. In addition to the excellent properties of natural graphite such as cold and heat resistance, corrosion resistance, and self-lubrication, expanded graphite also has softness, compression resilience, adsorption, ecological environment coordination, biocompatibility, radiation resistance that natural graphite does not have. characteristics such as sex.
The difference between flake graphite and earthy graphite
The degree of metamorphism of earthy graphite is deep, and it belongs to high-quality microcrystalline graphite. Most of it is graphite carbon. Strong acid-base effects.
Earthy graphite is also known as amorphous graphite or cryptic graphite. The crystal diameter of this graphite is generally less than 1 micron, and the crystal shape can only be seen under an electron microscope. It is microcrystalline graphite.
