Overview of high purity graphite powder
High purity graphite powder is the most stable form of carbon, in the isolation of oxygen conditions, its melting point above 3000℃ is one of the most temperature-resistant minerals. Graphite powder is a kind of mineral powder, mainly composed of carbon, soft, black gray; Greasy can pollute the paper. The hardness is 1 ~ 2, along the vertical direction with the increase of impurities the hardness can be increased to 3 ~ 5. The specific gravity is 1.9 ~ 2.3. The chemical properties of graphite powder are relatively stable at room temperature, insoluble in water, dilute acid, dilute alkali and organic solvents.
High purity graphite powder refers to the graphite powder containing more than 99.9% of carbon, high purity graphite powder carbon content is high, such a high purity graphite powder has good electrical conductivity, lubricity, high-temperature resistance, wear-resistance and other characteristics. Primarily used to determine how carbon compounds are formed in the application of thermal benchmarks. High purity graphite powder is mainly used in aviation, electronics, metallurgy, atomic energy, chemical industry, machinery, nuclear energy and other fields. The carbon content of high purity graphite is above 99.99%. High purity graphite can also be divided into nuclear graphite, coarse crystalline graphite, space graphite and fine crystalline graphite (maximum grain diameter less than 0.075mm).
Characteristics of high purity graphite powder
High purity graphite powder is made of high purity graphite processing cutting out, graphite particles granularity range in accordance with the processing way, graphite powder specifications and USES are associated, in graphite powder specifications, also not necessarily say, graphite powder mesh, the greater the graphite powder's particle size is smaller, the graphite powder quality is better, and to see the factor such as the carbon content of graphite powder, graphite powder, the higher the carbon content, Conductive properties of the graphite powder, high-temperature resistant performance is better, the specification and application of the graphite powder, in industrial production, it is very important to choose appropriate graphite powder specifications, so for the cost of production is good, the control of graphite powder specifications of the mesh big, the small grain size of graphite powder, its carbon content is high also, graphite powder has been used more widely.
What are the applications of high purity graphite powder?
The application of high purity graphite powder has an excellent performance in industrial production. High purity graphite powder is used in electric conduction, lubrication, metallurgy and other industrial production fields. In the production of high purity graphite powder, the impurity content should be strictly controlled from the beginning of raw materials, the raw materials with low ash content should be selected, and the increase of pollutants should be prevented as far as possible in the production process. However, the reduction of contaminants to the desired extent is mainly in the graphite chemical order. Graphitization occurs at high temperatures where the oxides of many impurity elements break down and evaporate. The higher the graphitization temperature, the more impurities discharged, the higher the purity of the high purity graphite powder products produced. High purity graphite powder uses its excellent electrical conductivity, lubricity, high-temperature resistance and other advantages.
High purity micron graphite particles have a very wide range of applications: Picture tube, a display of the electronic information manufacturing industry in the black conductive coating, composed of liquid crystal display device, sensor and black color on the resolver photosensitive coating, the color LCD plasma trichromatic boundary part of the flat panel display is used to enhance emission effect and color contrast, ultrafine tungsten, molybdenum wire drawing and another coating, High purity sub-micron graphite particles are widely used in many industries such as advanced lubricating oil and grease manufacturing, high-performance battery iron and nickel foam manufacturing and photographic film.
Special graphite coatings: water-based graphite coatings, conductive graphite coatings, dissolved graphite coatings, internal and external graphite coatings, drawing graphite coatings, lubricating graphite coatings, glass fiber coatings, TV graphite coatings and special coatings, a variety of non-metallic materials, nanomaterials production process, design, etc.
