Graphite is classified into six categories and has many applications.
Graphite is abundant in my country, and it’s widely distributed. However, many of the small and medium sized minerals are found there. Private small graphite miners have operated in my country, but their added value is low. After many years of hardwork, my country has invested in a large amount of money and scientific and technological personnel. The graphite reserves of my country have been used more efficiently after the reorganization and improvement of the graphite use. My country has now developed high-purity products such as expanded graphite (also known as Isostatic graphite), colloidal graphite (also known as fluorinated) graphite.
1. High purity graphite
High-purity carbon graphite is used in the chemical fertilizer, metallurgical, military, industrial, and pyrotechnic industries as a stabiliser, catalysts, and additives.
2. Isostatic Graphite
The graphite used to make isostatic graphite comes from a very pure graphite. It has a low coefficient of thermal expansion, excellent heat resistance, chemical resistance and good thermal conductivity. In the past fifty years, isostatic graphite has become a world-first product. It has not only achieved great success in civil applications, but also holds a prominent position in cutting-edge national defense. This is a brand new material, which is also eye-catching. It is mainly used for the following aspects.
(1) Heater to heat polysilicon ingots
As a result of the global warming, the awareness among humans to protect the Earth has increased. More and more people now prefer natural energy that does not emit carbon dioxide. In this trend, solar cell technology has become the “darling of the new age”. The ingot heater that is used during the manufacturing process must be made out of graphite.
Nuclear fission (high temperature gas-cooled) reactor
In order to meet the requirements of graphite as a moderator for high-temperature reactors that use gas cooling, it must resist radiation stress from deformation and have a high resistance to radiation creep. Therefore, a modular high temperature gas cooled reactor has been proposed. Modern ultra-high temperature reactors are characterized by high power density at high temperature. This raises the bar for new graphite materials. They must be of good quality and low cost, with high radiation damage tolerance and homogenization.
Nuclear fusion reactor.
Graphite’s special properties also play an important role in nuclear fusion. It can greatly reduce the metal particles in the material’s plasma, and therefore plays an important role in improving energy confinement. With the expansion of nuclear fusion, graphite material with high mechanical strength, good thermal conductivity, and a good discharge pulse are used as the first wall facing the plasma. Because graphite is low in atomic numbers and has low radiation losses, it is able to stabilize high-temperature plasma even when mixed with it.
(4) Electric discharge machining electrode.
In the electrodes for electric discharge machining, graphite electrodes offer many advantages. Although graphite is a good material, it has some drawbacks. For example, dust and wear can occur during cutting.
3. Expandable graphite
Also known as acidified or flake graphite. It is made from high-quality graphite. Expanded Graphite offers many advantages, such as high-temperature resistance, high-pressure resistance, good seal performance, and corrosion resistance for various media. It is a type of advanced seal material. It is mainly applied in the following areas.
The environmental protection field.
The hydrophobicity and lipophilicity of expanded graphite allows it to selectively remove nonaqueous solution from water. This feature is commonly used to remove slicks of oil from the surface. A large amount of oil can be absorbed by this product due to its molecular composition. After oil, the graphite can be agglomerated into blocks and floats on the ocean. It can also be recycled or reused, without causing any secondary pollution. Expanded graphite, in addition to its selective adsorption, has an inhibitory impact on air pollution. This includes the adsorption and removal of carbon dioxide.
Sealing Material
It is also known as “the sealing king” because it can be transformed into flexible graphite. This graphite has low thermal expansion coefficients, and doesn’t crack or soften at high temperatures.
4. Graphite fluoride
Graphite fluoride, a high-tech material with high performance and efficiency, is a research hotspot in the world. It is widely used for functional materials due to its unique properties and excellent performance.
(1) It is used as a releaser.
Graphite-fluoride has a low surface energy, which makes it a good release agent for metal moulds.
(2) Solid Lubricants
Fluorinated Graphite, with its low interlayer energy and low surface energy as well as good chemical and thermal properties, has outstanding lubricating characteristics and is ideal for harsh conditions like high temperatures, pressures and corrosive media.
Battery Raw Materials
It is very difficult to use fluorine in the active material of batteries that contain fluorine and lithium, because fluorine gas can be poisonous. Fluorinated Graphite is used for its excellent electrochemical properties when mixed with organic electrolytes. This makes it a popular material in the integrated circuit memory of cameras, computers and watches.
5. Colloidal graphite
One of the main features of colloidal graphite is its lubricity. The colloidal film of graphite has an excellent thermal insulation in the vertical direction. It is used widely in turbine propellers and hot steam cylinders. It is used to reduce static electricity in the electronics industry.
6. Graphene
Graphene consists of a hexagonal honeycomb-like lattice made up of hybrid orbitals and carbon atoms. This is a two-dimensional, one-atom thick material. It is a nanomaterial that has the highest level of hardness and toughness.
The special arrangement of its atomic structure has made it widely used.
(1) According to ultra-thin Graphene (single layer graphene almost transparent; its molecules are tightly packed, so that even the smallest of helium atoms can’t pass through), the strength is super strong, and it can be used in ultra-light armors, ultra thin and ultra light aircrafts, etc. .
(2) Its conductive atoms have a much higher speed than electrons that move in metal conductors. It can be made into graphene conductor agent.
Its thermal conductivity is superior to all known substances. Due to the rapid movement and movement of its conductive atoms, it can be applied in place of silicon as a component of future curved mobiles, photon sensors, and supercomputers.
Researchers have found that bacteria cannot grow on graphene but that human cells do not suffer any damage. Take advantage of it; graphene is great for bandages, packaging food, etc.
