Graphite powder and flake graphite?? The difference between earthy graphite and flake graphite

Founded in 2001, Chengdu Atech Specialty Graphite is a company specializing in carbon graphite processing. Our business philosophy is clear, that is, we will continue to focus on the processing and manufacturing of carbon graphite products now and in the future, providing reliable and high-quality carbon graphite products to customers in the following key industrial fields. - Photovoltaic, electronics and semiconductors - High temperature and vacuum electric furnace - Traditional industry (such as non-ferrous metallurgy, mold making, glass quartz, (glass) optical fiber, electrolysis (plating), cement, synthetic diamond tools, etc.) - Automobile and machinery field (such as manufacturing mechanical seals, vacuum pumps and compressors, etc.) - Carbon graphite for electrical engineering (such as carbon brushes for motors, grounding devices for locomotives, carbon slide plates for pantographs, etc.).

Flake graphite refers to the graphite molecules arranged in layers to form a flake structure, and graphite powder is a spherical structure composed of graphite molecules, the size is in the unit of mesh, you do the test to see how to use, if it is involved in the reaction, then the reaction contact area of graphite powder is greater than that of flake graphite, the reaction speed is not easy to control, if you do other uses you consider separately.

In addition to the above uses, Qingdao Huatai flake graphite powder can also be processed into ultra-fine graphite powder, nano graphite, colloidal graphite, expandable graphite and other graphite powder products.

There are mainly the following coarse differences between earthy graphite and flake graphite:

1. Different diameters: The diameter of soil-like graphite crystals is generally less than 1 micron, which is an aggregate of microcrystalline graphite. Flake graphite is generally 2 mm in size, with a maximum of 4 to 5 mm;

2. Different properties: the front yard surface of the soil-like graphite table is earthy, lacking luster, poor lubricity, and high grade. Flake graphite is a flake-like, thin-leaf-like crystalline graphite with obvious directional arrangement, which is consistent with the plane direction.

1. Because the chemical properties of graphite are very stable, graphite can be used as a pencil lead, pigment, polish, etc., and the words written with graphite can be stored for a long time.

2. Graphite has the property of high temperature resistance, so it can be used as a refractory material, for example, the crucible used in the metallurgical industry is made of graphite.

3. Graphite can be used as a conductive material, for example, carbon rods in the electrical industry, the positive electrode of mercury positive flowers, electric brushes, etc. are all made of graphite.

4. It is a wise choice to use graphite as a wear-resistant slip material instead of lubricating oil, graphite is often used as a lubricant in mechanical production, we all know that lubricating oil can not be used in the case of high temperature and high pressure, and graphite is different, graphite can still be used in a high-temperature environment.

5. The use of graphite has good chemical properties, which can be used in petrochemical industry, synthetic fibers, heaters, etc., not only with corrosion resistance, but also with good conductivity of graphite.

Graphite is a gray-black carbide with excellent electrical conductivity, oxidation resistance, acid and alkali resistance and corrosion resistance, so it is widely used in the electronics industry, aerospace industry, energy industry and medical technology. In the electronics industry, it can be used as an overlay in printed circuit boards or as a protective covering material for connectors. In the aerospace sector, it can be used as a thermal insulation material on aircraft or as a reinforcing material in composite materials.

In the energy industry, it can be used as a protective lining on the inner walls of nuclear reactors. In terms of medical technology, it can be used as a separator or a biological agent for internal surgeries in the human body.

Graphite can be used to make electrodes, coatings, seals, filter elements, etc. It can also be used in electronic components, nanotechnology, energy conservation and environmental protection. Graphite can also be used to make items such as matches, torches, batteries, and industrial applications such as smelting iron ingots.

Graphite is an allotrope of the element carbon, in which three other carbons (arranged in multiple hexagons arranged in a honeycomb pattern) are connected around each carbon atom to form a covalent molecule.

Since each carbon atom emits an electron, which can move freely, graphite is a conductor of electricity. Graphite is one of the softest minerals, and its uses include making pencil leads and lubricants. Carbon is a non-metallic element that is located in the second period of the periodic table, group iva.

Latin for carbonium, which means "coal."

Graphite is a carbonaceous crystalline mineral, and its crystalline lattice is a hexagonal layered structure. The distance between each mesh layer is human, and the spacing of carbon atoms in the same mesh layer is 1 42a. It belongs to the hexagonal crystal system with complete layered cleavage.

The cleavage plane is dominated by molecular bonds, and the attraction to molecules is weak, so its natural floatability is very good.

Graphite is an allotrope of the element carbon, in which three other carbon atoms (arranged in a honeycomb-like hexagon) are connected to each carbon atom around each other to form a covalent molecule. Molecular Formula: C

Graphite has the following special properties:

1) High temperature resistance: the melting point of graphite is 3850 50, the boiling point is 4250, even if it is burned by ultra-high temperature arc, the weight loss is very small, and the coefficient of thermal expansion is also very small. The strength of graphite increases with temperature, and at 2000, the strength of graphite doubles.

2) Electrical and thermal conductivity: The electrical conductivity of graphite is 100 times higher than that of general non-metallic minerals. Thermal conductivity exceeds that of metallic materials such as steel, iron, and lead.

The thermal conductivity decreases with increasing temperature, and even at extremely high temperatures, graphite becomes an insulator. Graphite is able to conduct electricity because each carbon atom in graphite forms only 3 covalent bonds with other carbon atoms, and each carbon atom still retains 1 free electron to transport the charge.

3) Lubricity: The lubricating performance of graphite depends on the size of the graphite flakes, the larger the flakes, the smaller the friction coefficient, and the better the lubrication performance.

4) Chemical stability: Graphite has good chemical stability at room temperature, and can resist acid, alkali and organic solvent corrosion.

5) Plasticity: Graphite has good toughness and can be milled into very thin sheets.

6) Thermal shock resistance: graphite can withstand drastic changes in temperature without damage when used at room temperature, and when the temperature changes abruptly, the volume of graphite changes little and will not cause cracks.
