Fluorinated carbon Usage And Synthesis

Description

Graphite fluoride is one of the research hotspots of new high-tech, high-performance and high-efficiency carbon/graphite materials in the world. With its excellent performance and unique quality, it is a wonderful flower in the family of functional materials.

Chemical Properties

1. Good chemical resistance. Chemical resistance is better than PTFE at room temperature. It is also stable to concentrated sulfuric acid and concentrated nitric acid, and insoluble in various organic solvents. However, hot concentrated sulfuric acid and hot alkali have certain invasion to it, and react with alkali metals and alkali halide compounds at high temperature to form fluorinated alkali and amorphous carbon.
2. Good thermal stability (only a small amount of weight loss is higher than 500 °C).
3. Good lubricating performance, the lowest friction coefficient among greases and solid lubricants (molybdenum disulfide, graphite, etc.)
4. Good electrical insulation, (CF)n resistivity is above 3×103Ω/cm.
5. The Mohs hardness is 1.0 to 2.06, and the particle size distribution is very wide, ranging from less than 1 μm to more than several millimeters.

Chemical Properties

-200 mesh, 99.9% pure; polymer [ALD94] [CER91]

Uses

Lithium anode batteries, lubricant chromatographic materials.

Definition

Fluorinated graphite cathode material.

Manufacturing Process

In the reaction system of graphite and fluorine, trace metal fluorides (LiF, MgF2, AlF3 and CuF2) are added as catalysts, and the synthesis can be carried out below 300 °C. Due to the addition of trace metal fluorides, the properties of graphite fluoride are changed, and the electrical conductivity is increased by an order of magnitude. The purity of graphite and fluorine gas is required to be above 99.4%, and the purity of catalyst is more than 98%.
