What is natural graphite? Natural graphite is a kind of non-metallic mineral, often symbiotic with quartz, feldspar, forming graphite-containing rocks, or generated in deep metamorphic coal seam. Natural graphite has good thermal conductivity, thermal conductivity between copper and iron; natural graphite has excellent electrical conductivity; natural graphite chemical stability, can resist most chemical reagents, it resistance to most of acid, alkali, salt; natural graphite oxidation resistance, high ignition point, also has good lubrication.
Main uses of natural graphite Natural graphite is mainly made of metal smelting crucible and various refractory products of metal smelting furnace, natural graphite lubricant such as steam engine, internal combustion engine, air compressor, bearing, slide, gear and other similar occasions; and can also be used for sand coating, paint, furnace agent, boiler treatment, explosive manufacturing, smoothness and other graphite creams. The difference between artificial graphite and natural graphite: The development of natural graphite crystal is more perfect, and the graphitization degree of scale graphite is more than 98%, while the graphitization degree of natural microcrystalline graphite is usually less than 93%.The development degree of artificial graphite crystals depends on the raw material and the heat treatment temperature. In general, the higher the heat treatment temperature, the higher the degree of graphitization. At present, the graphitization degree of artificial graphite produced by industry is usually less than 90%; natural scale graphite is a single crystal with simple tissue structure, only crystallographic defects and macro anisotropy. The grains of natural microcrystalline graphite are small, and the grains are disordered and have holes after impurity removal, which are isotropic macroscopically. Artificial graphite can be regarded as a multiphase material, including the graphite phase transformed by carbon particles such as petroleum coke or asphalt coke, the coal asphalt binder, particles accumulation or pores formed by coal asphalt binder after heat treatment; natural graphite usually exists in the form of powder and can be used alone, but usually combined with other materials. There are many forms of artificial graphite, both powder, fibrous and block, while the narrow artificial graphite is usually block, which needs to be processed into a certain shape when used. Price of natural graphite The different price of natural graphite purity is also different. The market price of natural graphite is in the process of dynamic change.
