What is high-purity graphite powder? High-purity graphite powderis high carbon content, high purity graphite powder. Therefore, it is called high -purity graphite powder. The high -carbon content of high -purity graphite powder means that high temperature resistance and conductivity are better than ordinary graphite powder. This depends on carbon content and is caused by different production and processing processes.
Use of high-purity graphite powder Graphite powder is one of the important raw materials for producing pencil lead; It is also the raw material for making refractory materials and coatings; It is also an important carbonaceous material, widely used in the metallurgical industry as a deoxidizer for steelmaking and in the manufacture of synthetic diamonds and refractories; In addition, it is also used as an additive for coating fillers and abrasives.
Preparation of high-purity graphite powder
The mineral processing method of crystalline graphite: the natural floatability of crystalline graphite is good, and flotation is a common method for mineral processing. In the flotation process, kerosene, No. 2 oil and No. 4 oil are used as foaming agents, lime and sodium carbonate are used as regulators, and sodium silicate is used as an inhibitor.
The mineral processing method of aphanitic graphite: aphanitic graphite crystal is very small. Graphite particles are often embedded in clay, which is difficult to separate and increases the separation cost. Because the carbon content of the raw ore is generally about 60% - 80%, and the grade is high, many graphite mines directly crush the mined ore into graphite powder products.
Safety of high-purity graphite powder Contact with natural graphite may cause progressive or disabling pneumoconiosis, with symptoms including headache, cough, depression, loss of appetite, dyspnea, and black sputum. Some poisoned people may suddenly become disabled after years without symptoms. Artificial graphite can also cause pneumoconiosis. The staff shall be well protected. During storage and transportation, do not come into contact with strong oxides such as fluorine, chlorine difluoride, and potassium perchloride.
Price of high-purity graphite powder High-purity graphite powder particle size and purity will affect the product's price, and the purchase volume can also affect the high-purity graphite powder cost. A large amount of large amount will be lower. The high-purity graphite powder price can be found on our company's official website.
