What is graphite fluoride?
Graphite fluoride is a material formed by the reaction of fluorine gas with graphite.
How is graphite fluoride formed?
Graphite fluoride is formed through a high-temperature reaction of fluorine gas with graphite, charcoal, or pyrolytic carbon powder.
What is the chemical structure of graphite fluoride?
The chemical structure of graphite fluoride is expressed as (CFx) n, where x is an indefinite value between 0 and 1.25.
What are the unique properties of graphite fluoride?
Graphite fluoride has low surface free energy, good thermal and chemical stability, unique lubricity, hydrophobicity, and oil repellency, and excellent chemical and thermal stability.
What are some applications of graphite fluoride?
Some applications of graphite fluoride include high energy density cathode material in lithium batteries, lubricant additive, weather-resistant additive for paints, oxidizing agent and combustion modifier in rocket propellants and pyrolants, water and oil repellent coating, anti-fouling agent, thermal management material, catalyst support, conductive filler, and additive in the production of high-performance plastics.
How does the ratio of C to F in the formula affect the properties of graphite fluoride?
The ratio of C to F in the formula of graphite fluoride affects its properties. CF (1-1.25) is high fluorinated graphite, while CF (0.5-0.99) is low fluorinated graphite.
What are the properties of high fluorinated graphite?
High fluorinated graphite has excellent thermal stability, is an electrical and thermal insulator, is resistant to corrosion by strong acid and alkali, and has ultra-high lubricating performance.
What is the appearance of low fluorinated graphite?
Low fluorinated graphite has a gray black appearance.
Can low fluorinated graphite be used as a lubricant?
Low fluorinated graphite is usually not used as a lubricant due to its poor thermal stability.
In what fields is graphite fluoride widely used?
Graphite fluoride is widely used in military, aviation, aerospace, metallurgy, mechanical and electrical, chemical, and other fields.
