Six types and uses of graphite
Although graphite is abundant in my country, it’s also widely available. Many of these minerals are smaller and more compact than the larger ones. Private small graphite mines have occurred, although the additional value of graphite-derived products is very low. The country has made significant investments in scientific and technical personnel and funds after many years of hard labor. My country’s graphite reserves have become more efficient after the reorganization and improvement in graphite usage. My country is now producing high-purity, Isostatic, expanded, fluorinated, fluorinated, and colloidal graphite as well as other high-performance graphite materials.
1. High purity graphite
High-purity graphite has a carbon content above 99.99% and is used for pyrotechnic materials (military industrial), advanced refractory metals in the metallurgical industries, Chemical fertilizer Industry catalysts, additives, etc.
2. Isostatic graphite
It is made from very pure graphite. You will find it has a low thermal expansion coefficient and excellent heat resistance. It also exhibits good electrical and thermal conductivity. It is an innovative product that has been developed in the last 50 year. Not only is it a remarkable product in civil use but it has a prominent position in national defense. It’s a novel material that is very eye-catching. These are the main uses of it.
(1) Heater to heat the polysilicon ingot furnace.
With the increase in global warming over recent years humans have become more conscious of the need to protect the planet. As such, more people are choosing natural energy sources that don’t emit CO2. This is why solar cells have been the “darling” in the new era. Itostatic graphite must be used to make the furnace ingot heaters.
(2) A high temperature, gas-cooled reactor for nuclear fission (nuclear fission).
Since graphite is used in high-temperature, gas-cooled reactors as a moderator must be resistant to radiation and deformation. A modular high-temperature-gas-cooled reactor has been proposed. Modern ultra-high-temperature reactors are characterized by high power density, high temperature and radiation damage tolerance. The new graphite material generation must meet higher standards: low cost, high quality, homogenization and product homogenization.
(3) Nuclear Fusion Reactor
Graphite is also important in the construction of nuclear fusion engines because it has special properties. Because it can decrease the amount of metal impurities found in material plasma, graphite plays an important role in improving its energy confinement. As the nuclear fusion device’s power increases, graphite is becoming the primary wall material in plasma. These materials have high thermal conductivity and mechanical strength and exhibit good discharge pulse effects during their application. It can also keep plasma high temperature stable because of its low atomic numbers and low radiation losses.
(4) Electric discharge machining electrode.
One of the advantages graphite electrodes has in electrodes for electric discharge machining is its lightness and ease of use. But graphite electrodes are not without their limitations. For example, they can be prone to wear or dust from cutting.
3. Expandable graphite
An interlayer compound that has been treated with acidic oxygenizers such as sulfuric acid, nitric acids, hydrogen peroxide or potassium permanganate, acidified graphite can be made from high-quality, natural flake graphite. Many advantages are available to expanded graphite, including high temperature resistance and high pressure resistance as well as good sealing performance. It also resists corrosion of different media. It’s a novel type of high-performance sealing material. It’s primarily used in the following locations.

(1) Environmental protection.
Expanded graphite is hydrophobic and has lipophilicity that can selectively remove water. This is a common feature used to clean slick oil from the sea floor. Due to its molecular arrangement, there is high adsorption. The oil can then be broken down into small blocks that can be floated on the sea. It can also be recycled or reused, without any secondary pollution. Additionally to its selective adsorption within the liquid phase of graphite, it also inhibits air pollution by absorbing carbon dioxide gas.
(2) Sealing material
The flexible graphite from expanded graphite can also be used to seal materials (small thermal expansion, no brittleness and no cracking at lower temperatures; softening is minimal, but no creep at higher temperature).
4. Graphite fluoride
Graphite Fluoride is one the most important research areas for new graphite, carbon, and graphite material. It is widely used for functional materials and has outstanding performance.

(1) Use as a release agent.
Graphite Fluoride exhibits low surface energy. This makes it a good release agent for metal molds like powder molding and die casting.
(2) Lubricants solid.
Fluorinated graphite’s low interlayer energy, lower surface energy, and good chemical properties make it ideal for use in harsh environments such as high temperature and pressure.
(3) Raw materials for battery batteries
Fluorine-lithium batteries are high in energy. However, fluorine is toxic and is not recommended for use as an anode material. Fluorinated graphite, which has good electrochemical properties, is widely used for integrated circuit memories in computers, watches, and cameras.
5. Colloidal graphite
One of the main characteristics of colloidal graphite is its 1Lubricity. Colloidal graphite can be used to form a lubricating layer on friction machines that have high frictional strengths. This will reduce friction resistance as well as the temperature of friction. 2 Heat insulation. 3 Evenly formed and with excellent thermal and electrical conductivity, the film uses colloidal graphite. It’s used in electronics to reduce reflection and eliminate static electricity.
6. Graphene
Graphene is a hexagonal honeycomb containing carbon atoms as well as sp2 and sp2 mixed orbitals. It has only one carbon-atom thickness. It’s the most hardy and toughest nanomaterial found to date.
Because of its unique arrangement structure and atomic characteristics, it is very widely used.
(1) Ultra-thin graphene can be made into ultra-light body armor or ultra-thin aircraft. .
(2) Their conductive electrons have an extremely fast speed. This is because they can move free in the crystallinity and far surpass the speed of the electrons in semiconductors and metal conductors. It can be made into graphene, a conductive agent.
(3) It is thermally more efficient than all other substances known, and because of the speed of its electrons moving, it can be studied and used instead of silicon to create future supercomputers, photon sensors, and curved smartphones.
(4) Other applications. Researchers discovered that graphene cannot be grown on bacteria cells, but it is safe for human cells. This means graphene is suitable for food packaging and bandages.
