Wide application of high purity graphite

The flotation method is one of the conventional mineral purification methods with less energy consumption and reagent consumption and lower cost. This is a major advantage of the flotation method to purify graphite. However, when using the flotation method to purify graphite, only the grade of graphite can be improved. achieve limited improvement. For flake graphite, the use of multi-stage grinding not only cannot completely dissociate the monomer but also is not conducive to protecting the large flakes of graphite. Therefore, it is neither economical nor scientific to further improve the graphite grade by flotation. For high-carbon graphite with an amount of more than 99%, pure graphite must be purified by chemical methods.

Wide application of high purity graphite powder

1. High-purity graphite powder has a dense and uniform structure and high chemical stability. It has a unique property of high temperature resistance. High-purity graphite powder has good dimensional stability under high temperature resistance conditions and has a good protective effect on workpieces.

2. The carbon content of high-purity graphite powder is more than 99.9%, and the carbon rod in the carbon arc gouging rod is used as an electrode. It is an excellent non-metallic material. High-purity graphite powder also has the characteristics of high density, high strength and high purity. The electrode made of high-purity graphite has low ash content, good conductivity, heat resistance and corrosion resistance. It is a chemical silicon The first choice in smelting, so high-purity graphite powder has broad application prospects in metal silicon smelting.

3. As a deep-processing product of graphite, high-purity graphite powder plays an important role in advanced sealing, composite materials, nuclear industry, aerospace and other fields.

4. High-purity graphite powder has the advantages of high temperature resistance, good electrical and thermal conductivity, lubricity, chemical stability, and good wear resistance. It can be used as raw materials for artificially synthesized crystal silicon carbide and boron carbide, as well as coatings for stealth aircraft and chemical, electronic, and mechanical applications. And other industrial fields, has a very wide range of uses.

4. The way graphite is manufactured, separates carbon thin layers by chemical or mechanical exfoliation, forming a dry powder that may cause inhalation and exposure. If these dry powders (also known as material fragments) are inhaled into the body and come into contact with human cells, these material fragments are likely to cut through human cells and be absorbed by them, thereby endangering human health.

5. Reduction of incomplete graphene oxide nanoparticles can have environmental impacts if it finds its way into surface or groundwater resources.

Stability of high purity graphite powder

1. High-purity graphite powder is a graphite mineral with different crystal forms. It has different industrial values ​​and uses. High-purity graphite powder has the characteristics of high strength, small resistivity, easy precision processing and high temperature resistance. It is a good inorganic non-metallic material.
