Application of Flake Graphite

Application of Flake Graphite

Flake graphite is natural crystal graphite, its shape is like fish phosphorus, belongs to hexagonal crystal system, is layered structure

Flake graphite crystal integrity, thin and good toughness, excellent physical and chemical properties, with good thermal conductivity, electrical conductivity, thermal shock resistance, corrosion resistance, etc. As a new nanometer carbon material, flake graphite not only has excellent electrical conductivity and adsorption, but also has good chemical stability, so it has a wide range of applications in electrode materials. Flake graphite is widely used in refractory and coating for gold industry. Such as magnesia carbon brick, crucible and so on. Military industry pyrotechnics material stabilizer, smelting industry desulfurization accelerating agent, light industry pencil lead, electrical industry carbon brush, battery industry electrode, fertilizer industry catalyst, etc. Flake graphite after deep processing, and can produce graphite emulsion, used in lubricants, mold release agent, wire drawing agent, conductive coating, etc. Also can produce expanded graphite, used in flexible graphite products raw materials, such as flexible graphite seals and flexible graphite composite products.

Graphite flakes were used as conductive fillers to prepare polymer-based conductive composites. Flake graphite is one of the conductive filler materials. The more commonly used carbon black has the advantages of good conductivity, low friction loss, and low pollution. Moreover, the addition of flake graphite can greatly improve the conductivity of polymer materials, making polymers from insulators to semiconductors. Therefore, it has important application value in conductive composites.
