Characteristics and Application of High Purity Graphite
High purity graphite means that the carbon content of graphite is more than 99.99%. High purity graphite has the advantages of high strength, high density, high purity, good seismic resistance, high temperature resistance, oxidation resistance, small resistance coefficient, corrosion resistance, easy precision machining, etc. It is an ideal inorganic non-metallic material, which is used for processing electric heating elements, EDM graphite, sintering molds, electronic tube anodes, etc, It is widely used in high-grade refractory materials and coatings in metallurgical industry, explosive materials stabilizer in military industry, pencil lead in light industry, carbon brush in electrical industry, electrode in battery industry and catalyst additive in fertilizer industry. After deep processing, high-purity graphite can also produce high-tech products such as graphite emulsion, graphite sealing materials and composites, graphite products, graphite anti-wear additives, etc, It has become an important non-metallic mineral raw material for various industrial sectors.
The high-purity graphite flakes have complete crystals, thin sheets, good toughness, excellent physical and chemical properties, and good heat conductivity and temperature resistance. They are widely used in metallurgy, chemical industry, aerospace, electronics, machinery, nuclear energy and other industrial fields, especially high-purity graphite with large specifications and high quality. As an alternative material, high-purity graphite has broad application space and broad application prospects in high-tech and new technology fields.
There are two purification methods for high-purity graphite, one is wet purification, and the other is fire purification. Wet purification includes flotation method, acid base method and hydrofluoric acid method; Pyro purification includes chlorination roasting method and high temperature method.
After the project is completed, the annual output of spherical graphite will be 2,000 tons, and the annual sales income will be 120 million yuan.
Shandong is one of China's important industrial base provinces. Especially since the reform and opening up, Shandong has not only occupied an important position in the light industry, but also the chemical industry has developed rapidly. After more than two decades of reform and opening up, it has already had a solid foundation.
In 2011, the export situation of flake graphite was relatively sluggish.
Spherical graphite is made of high-quality high carbon natural flake graphite by using advanced processing technology to modify the surface of graphite to produce graphite products with different fineness and oval shape.
High purity graphite means that the carbon content of graphite is more than 99.99%.
