Graphite Material
Carbon Graphite Material
This kind of silicon carbide graphiteis molded by 10000 tons hydraulic press and then roasted for several months to make the finished product. Therefore, carbon graphite composite materialhas high purity and good physical properties. It is widely used in the metallurgical industry, advanced refractory coating, military pyrotechnic material stabilizer, pencil lead for light industry, carbon brush for electronic industry, an electrode for the battery industry, catalyst additive for the chemical fertilizer industry, etc.
High Purity Graphite Material
High purity carbon and graphiteis a kind of graphite with high purity, and its content is more than 99.9%. It has the advantages of small resistance coefficient, high-temperature resistance, corrosion resistance, oxidation resistance, thermal shock resistance, good conductivity, small thermal expansion coefficient, self-lubrication, easy precision machining, and so on.
High Purity Graphite Material
Medium And Coarse Graphite Material
The particle size of medium and coarse graphite raw materials is 0.2, 0.4, 0.8, 2, and 4mm, and the density is between 1.55 and 1.75. It has the characteristics of low resistivity, oxidation resistance, corrosion resistance, high-temperature resistance, and good conductivity.
Medium And Coarse Graphite Material
Isostatic Pressing Graphite Material
Isostatic pressing graphite material is made of high-quality petroleum coke and asphalt coke as the main raw materials through pulverization (the average particle diameter is less than 25) μm) Graphite products are made by, kneading, binding, isostatic pressing, roasting, impregnation, graphitization, and other processes.
Graphite purification: there are two methods, chemical purification and physical purification.
The basic principle is to make impurities (mainly silicate minerals) in graphite react with caustic soda (NaOH) at a high temperature above 500 ℃ to form water-soluble reactants. The reactants can be leached with water to remove some impurities. Another part of impurities, such as iron oxide, can be neutralized with HCl after alkali melting to form soluble ferric chloride, which can be removed by washing with water.
- ℃, so that the ash (i.e. impurities) can be volatilized, so as to improve the concentrate grade. High purity graphite with 99.9% grade can be obtained by high-temperature purification.
