High purity graphite

High purity graphite is also called molded graphite, which means that the carbon content of graphite is more than 99.99%, which has good electrical conductivity, high-temperature resistance, oxidation resistance, low resistance coefficient, corrosion resistance, high purity, self-lubrication, thermal shock resistance, isotropy, easy to be machined and so on. High purity graphite flake are crystal complete, thin and tenacity, excellent physical and chemical properties. They are ideal inorganic nonmetallic materials. They are widely used in aerospace, solar photovoltaic and semiconductor, continuous casting, cemented carbide and electronic mold sintering, EDM, glass, machinery, energy, and other industries.

Purification method of high-purity graphite

The purification methods of high purity graphite are divided into two categories: one is wet purification, including flotation, acid-base, and hydrogen acid; The second is the purification by fire method, including chlorination roasting method and high-temperature method.

High purity graphite has unique advantages in processing and manufacturing electric heating elements, structural casting mold, crucible boat dish for smelting high purity metal, heater for single crystal furnace, graphite for EDM, sintering mold, the anode of the electronic tube, metal coating, graphite crucible for semiconductor technology, graphite anode and grid for emission electron tube, thyratron and mercury arc rectifier. Especially, as a substitute material, high-quality graphite with large specifications and high quality has a wide application space in high-tech and new technology fields and has a wide application prospect.

High heat conduction nano-scale carbon powder is a kind of synthetic high-purity graphite. Compared with natural high-purity graphite, it has higher purity, smaller particle size, and thickness within the nanometer scale. However, its radial width can reach several to dozens of microns, with a large shape ratio, and maintains the original planar carbon hexavalent ring conjugated crystal structure of graphite, with excellent mechanical strength Electrical conductivity, thermal conductivity, and good lubrication, high temperature, and corrosion resistance.

Potential applications of high-purity graphite

It is widely used in refractories and coatings in the metallurgical industry, pyrotechnics stabilizer in the military industry, pencil lead in the light industry, carbon brush in the electrical industry, electrode in the battery industry, catalyst additive in the chemical fertilizer industry, etc. After deep processing, high-purity graphite can also produce high-tech products such as graphite emulsion, graphite sealing materials, and composites, graphite products, graphite antifriction additives, etc., becoming important non-metallic mineral raw materials in various industrial sectors.

The production process of high purity graphite can be divided into one immersion and one baking graphite, two immersion and three baking graphite, three immersion and four baking graphite, four immersion and five baking graphite, etc. the density of two immersion and three baking graphite is more than 1.7, and that of three immersion and four baking graphite is more than 1.8.Significant characteristics of high-purity graphite

Significant characteristics of high-purity graphite

High purity graphite has good electrical conductivity, high-temperature resistance, corrosion resistance, high purity, self-lubrication, anti thermal shock, isotropy, easy to precision machining, and other excellent characteristics. It is widely used in aerospace, solar photovoltaic and semiconductor, cemented carbide and electronic mold sintering, EDM, glass, medicine, energy, and other industries.

High purity graphite products are made of various properties of high purity graphite. The high-temperature resistance of high purity graphite is used in industry to make high purity graphite crucible. High-purity graphite crucible can melt precious metals. According to the high-temperature resistance of high purity graphite products, the proportion is small, so it is widely used in manufacturing solid-fuel rocket nozzles, These are the uses of high purity graphite products. indispensable Import High purity carbon products are new material products. Based on special thermal equipment and purification technology, high-purity carbon products will be marketed.
