99.9% Graphite Powder flake graphite powder Crystalline Flake Graphite

production

High purity graphite refers to graphite powder containing more than 99.9% carbon, high purity graphite of high carbon content, such high purity graphite has good conductivity, lubrication, high-temperature resistance, wear resistance, etc.

The use of high purity graphite in the field of industrial production has excellent performance. High purity graphite is used in conductive, lubrication, metallurgy, and other industrial production fields. High purity graphite production, from the beginning of the raw materials, should be strictly controlled the content of impurities, choose low ash raw materials, and in the production process to prevent the increase of pollutants as far as possible. However, the reduction of contaminants to the degree required is primarily in the graphite chemical sequence. Graphitization occurs at high temperatures, where the oxides of many impurity elements will decompose and evaporate. 

2. Chemical stability: Graphite in the room temperature has excellent chemical durability, acid resistance, alkali resistance, and resistance to organic solvent corrosion.

3. Thermal shock resistance: Graphite in the room temperature when used to withstand the dramatic changes in temperature without destruction, temperature mutation, the volume of graphite changes little, will not produce cracks
