Graphite fluoride what are the main application fields

The compound of graphite and fluoride is widely used and has important applications in many fields.

First, in the field of batteries, its efficacy is significant. Graphite fluoride has unique electrochemical properties and can be used as a battery electrode material. Because it can improve the charging and discharging performance of batteries and increase the energy density of batteries, it is highly valued in the development and manufacture of new batteries such as lithium-ion batteries. This is because batteries are widely used in today's society, from daily mobile devices to large-scale equipment such as electric vehicles. The application of graphite fluoride in this field can make batteries perform better and last longer, meeting people's needs for efficient energy storage.

Second, in the field of lubrication, graphite fluoride also performs well. It has good lubrication characteristics and can be used as a high-quality lubricant. Whether it is the lubrication of various precision components in mechanical manufacturing, or the requirements for high-performance lubricating materials in the aerospace field, graphite fluoride can be competent. Because it can effectively reduce the coefficient of friction, reduce component wear, prolong the service life of mechanical equipment, and ensure the stable and efficient operation of equipment.

Furthermore, in the field of material surface modification, graphite fluoride can play a key role. Applying it to material surface treatment can give materials special properties such as hydrophobic, oily, and corrosion resistance. For example, in the surface treatment of building materials, after graphite fluoride treatment, the material can resist wind and rain erosion and prolong the service life of the building; in the surface treatment of fabrics, the fabric can have functions such as waterproof and anti-fouling, and improve the practicality and aesthetics of the fabric

In addition, in the field of electronic devices, graphite fluoride can be used to manufacture special electronic components due to its unique electrical properties. It can meet the development needs of electronic devices for high performance and miniaturization, and help electronic technology continue to advance, promoting the performance improvement and function expansion of electronic devices such as integrated circuits and sensors.

What are the physical properties of Graphite fluoride?

Graphite is made of fluoride, and its physical properties are very different. Graphite is inherently rich, and each carbon atom has a common dense phase, and it depends on the weak Vandal-E phase. Therefore, graphite has a good slippery feeling, and it is good.

graphite fluoride is reversed, resulting in graphite fluoride, and its properties are very large. In terms of external properties, it is often light gray to black powder, and the dark gray of graphite is slightly different.

One of them is the hardness, and the hardness of graphite fluoride is greatly increased. The action of fluorine atoms and carbon atoms makes it difficult to change and increase the force. It is no longer easy to slip like graphite, so the hardness is improved, which has the characteristics of graphite.

Second, the properties of graphite are also degraded. Graphite can quickly migrate along the carbon atom due to the common properties of carbon atoms, and the properties are good. However, in graphite fluoride, fluorine atoms form a common structure, restricting the migration of carbon atoms, and the performance is greatly reduced. The density of graphite fluoride is even close to that of graphite.

Third, in terms of qualitative aspects, graphite has a certain degree of qualitative properties, but it can still be reversed under special conditions such as oxidation or high temperature. Graphite fluoride is formed due to the stability of fluorine atoms, and the polymorphism is inert, and the qualitative properties of graphite are higher.

Fourth, in terms of density, due to the large amount of fluorine atoms, coupled with the combination of carbon atoms, the density of graphite fluoride is increased compared with that of graphite. On the




<, graphite fluoride has special properties in terms of hardness, durability, chemical quality and density due to the inverse effect of graphite fluoride.

Graphite fluoride is chemically stable?

The chemical properties of the compounds formed by graphite and fluoride are stable to a certain extent. The combination of the two gives graphite fluoride, which has a unique structure and different properties from when graphite and fluoride exist alone.

In graphite fluoride, fluorine atoms form bonds with graphite carbon atoms, causing its chemical stability to change. Fluorine is extremely electronegative, and when it forms bonds with carbon, it attracts electrons very strongly, making the bond energy quite high. This strong bond makes graphite fluoride not easy to react with common chemical reagents, and it can maintain a stable state at room temperature and pressure.

And the original layered structure of graphite also enhances its structural stability due to the insertion of fluorine atoms, and the layer spacing may change. Although fluorine is highly oxidizing, in the specific structure of graphite fluoride, its reactivity is bound. Common oxidation and reduction reagents are difficult to easily break its structure and change its chemical composition.

However, the stability is not absolute. If environmental conditions are extreme, such as high temperatures, high concentrations of strong oxidants or reducing agents, the stability of graphite fluoride may also be challenged. At high temperatures, the bond energy or insufficient to maintain structural stability, atomic vibration intensifies, causing chemical bonds to break, compound decomposition or other chemical reactions.

Overall, under common conditions, the chemical properties of graphite fluoride are relatively stable, but under extreme conditions, its stability is tested, showing the possibility of chemical changes.

Graphite fluoride preparation methods

The preparation methods of graphite and fluoride are ancient and have been explored and improved by many parties.

First, the direct synthesis method. Take pure graphite and place it in a special reaction vessel. The high-purity fluorine gas is introduced into the vessel slowly through precise regulation of the flow rate. This process requires strict control of the reaction temperature and pressure, and the temperature should be maintained at a specific range, such as between hundreds of degrees Celsius. The pressure must also be adapted to promote the full reaction of graphite and fluorine gas. Fluorine gas is extremely active. After contacting graphite, fluorine atoms can be embedded in the graphite layer to form graphite fluoride. Although this method is direct, it requires strict control of the reaction conditions. If you are not careful, it is easy to cause the reaction to go out of control.

Second, the indirect synthesis method. First, graphite is pretreated with specific chemical reagents to change its surface properties and enhance its reactivity. Subsequently, fluorine-containing compounds are selected to replace fluorine gas for reaction. For example, some stable organic fluorides are selected and reacted with the pretreated graphite under the action of appropriate catalysts. This process is relatively mild, easy to control, and can reduce the risk of reaction. However, the steps are more complicated, requiring fine operation of each link, and the choice and dosage of catalysts also have a great impact on the quality of the product.

Furthermore, vapor deposition method. In a vacuum environment at high temperature and low pressure, a gaseous fluorine-containing precursor is coexisted with a graphite substrate. The fluorine-containing precursor is thermally decomposed, and fluorine atoms are deposited on the surface of graphite in a gaseous form, and gradually combined with graphite. This method can precisely control the growth and structure of the product, and the graphite fluoride produced is of high quality and can achieve uniform preparation in a large area. However, the equipment requirements are extremely high and the cost is expensive, which limits its large-scale application.

Graphite fluoride in the market price

It is difficult to generalize the price of graphite and fluoride in the market. The price is influenced by various factors and is complicated.

The first to bear the brunt is the purity of the product. If the purity of graphite and fluoride is extremely high, it is suitable for high-end technology fields, such as electronic chip manufacturing, aerospace equipment, etc., its price will be high. Due to the complex production process of high-purity products, fine control and high-end equipment are required, and the cost has increased greatly. For example, the price of high-purity fluorinated graphite can reach hundreds or even thousands of yuan per gram.

Furthermore, the form of the product is also related to the price. Powder, flake, block and other different forms have different prices due to differences in preparation difficulty and use. Powder or easier to prepare, a wide range of uses, or relatively easy price; and specific shapes and specifications of products, if special processing is required, the price will rise.

The market supply and demand situation is also the key. If at some point, the electronics industry, new energy fields, etc. have a surge in demand for graphite-fluoride materials, but the supply is limited, according to market rules, prices are bound to rise. On the contrary, if supply exceeds demand, prices will decline.

The difference between the origin and the manufacturer also leads to price differences. Manufacturers with advanced technology, large scale and cost advantages may have more competitive product prices. In remote places, due to factors such as transportation costs, the price of their products may increase by a few cents.

Overall, common graphite-fluoride products, for industrial use, cost several hundred yuan per kilogram; if they are high purity and special specifications, the price depends on the specific situation, from several thousand yuan per kilogram or even higher, which is difficult to determine.
