Product Description:

Characteristics of graphite in Dongguan
At normal temperature, the chemical properties of carbon are relatively stable, and it is insoluble in water, dilute acid, dilute alkali and organic solvents; React and burn with oxygen at different temperatures to generate carbon dioxide or carbon monoxide; Among halogens, only fluorine can react directly with carbon; Under heating, simple carbon is easy to be oxidized by acid; At high temperatures, carbon can also react with many metals to form metal carbides. Carbon is reductive and can smelt metals at high temperatures.

Graphite is a crystalline mineral of carbonaceous elements, and its crystalline framework is hexagonal layered structure. The distance between each mesh layer is 3.40 Å, and the spacing of carbon atoms in the same mesh layer is 1.42 Å. It belongs to hexagonal crystal system with complete layered cleavage. The cleavage plane is dominated by molecular bonds and has weak attraction to molecules, so its natural floatability is very good.

Graphite, diamond, carbon 60, carbon nanotube and so on are all simple substances of carbon element, which are allotropes of each other. Imported graphite materials

Carbon element
Carbon is a very common element, which widely exists in the atmosphere and the earth's crust in various forms. Carbon has been recognized and used for a long time, and a series of carbon compounds - organic matter - are the root of life. Carbon is one of the components of pig iron, wrought iron and steel. Carbon can combine itself chemically to form a large number of compounds, which are important molecules in biology and commerce. Most molecules in organisms contain carbon. Dongguan graphite

Carbon compound
Carbon compounds are generally obtained from fossil fuels, and then separated and further synthesized into various products required for production and life, such as ethylene and plastics.

Form of existence
There are various forms of carbon, including crystalline carbon such as diamond and graphite; Amorphous carbon such as coal; There are complex organic compounds such as animals and plants; Carbonate such as marble. The physical and chemical properties of elemental carbon depend on its crystal structure. The crystal structure of diamond with high hardness is different from that of graphite with soft and smooth, and each has its own appearance, density, melting point, etc.

Morphological characteristics
Graphite soft, black gray; It has a greasy feeling and can contaminate the paper. The hardness is 1-2, and the hardness can increase to 3-5 with the increase of impurities in the vertical direction. The specific gravity is 1.9 ~ 2.3. The specific surface area is concentrated in the range of 1-20m2 / g. under the condition of oxygen isolation, its melting point is above 3000 ℃, and it is one of the most temperature resistant minerals. It can conduct electricity and heat.

There is no pure graphite in nature, which often contains SiO2, Al2O3, FeO, Cao, P2O5, CuO and other impurities. These impurities often appear in the form of quartz, pyrite, carbonate and other minerals. In addition, there are gas parts such as water, asphalt, CO2, H2, CH4 and N2. Therefore, in the analysis of graphite, the content of volatile matter and ash must be determined at the same time in addition to the content of fixed carbon. Dongguan graphite
