What are the characteristics of natural flake graphite C powder

The flake graphite has complete crystals, thin flakes and good toughness, excellent physical and chemical properties, good thermal conductivity, electrical conductivity, thermal shock resistance, corrosion resistance, etc.

Natural flake graphite C powder distribution

In December 2015, geological prospectors discovered a super-large scale graphite mine in Alxa League, Inner Mongolia. The total amount of proven graphite resources was 130 million tons, accounting for about 7.3% of the global recoverable reserves. Grade 5.45%. According to reports, such high-grade, ultra-large-scale graphite deposits are rare in China.

According to the 2013 report of the US Geological Survey, the global amount of large flake graphite minerals is less than 5 million tons. The amount of large scale graphite minerals found in the Chahanmuhulu graphite mining area in Alxa Left Banner is as high as 7.03 million tons.

Overview of natural flake graphite C powder

Flake graphite is a natural crystalline graphite, similar to fish phosphorus, belonging to the hexagonal crystal system, with a layered structure, with good high temperature resistance, electrical conductivity, thermal conductivity, lubricity, plasticity and acid and alkali resistance. -Pure high carbon natural flake graphite C powder CAS 7782-42-5 is prepared by laser ablation and is widely used in conductive coatings, glass manufacturing, lubricant formation, metal alloys, nuclear reactors, powder metallurgy and structural materials.

Application of natural flake graphite C powder

Natural graphite is mainly used in refractory materials, steelmaking, expanded graphite, brake pads, casting surfaces and lubricants. Natural graphite has found use as a marking material ("lead") for common pencils, zinc-carbon batteries, motor brushes, and various applications. Aluminum/graphite composites for engine bearings, pistons and cylinder liners; carbon sorbents for gas chromatography; copper/graphite and silver/graphite nanocomposites for brushes and contact strips; inorganic fillers (graphite/polymer nanocomposites); graphite/polymer nanocomposites, support materials for precision metal powder catalysts that enhance electrical conductivity; and metal matrix composites that reduce friction.

Flake graphite is widely used in advanced refractories and coatings in the metallurgical industry. Such as magnesia carbon bricks, crucibles, etc. Stabilizers for military pyrotechnic materials, desulfurization accelerators in the smelting industry, pencil leads in the light industry, carbon brushes in the electrical industry, electrodes in the battery industry, catalysts in the fertilizer industry, etc. After further processing, flake graphite can produce graphite emulsion, which can be used in lubricants, mold release agents, drawing agents, conductive coatings, etc. It can also produce expanded graphite, which is used as raw material for flexible graphite products, such as flexible graphite seals, flexible graphite composite products, etc.

As a functional filler of coatings, flake graphite is mainly used in anti-corrosion coatings, fire-retardant coatings and conductive coatings. Resistant to chemicals and solvents; chemical pigments such as zinc yellow are added to the formula for better rust prevention.

Graphite flakes can be directly used as carbon-based conductive fillers, and can also be made into composite conductive fillers for conductive coatings. However, due to the large amount of graphite flakes added, the performance of the coating will become brittle, and its application will be affected. Therefore, measures are taken to further improve the conductivity of graphite and effectively reduce the amount of graphite flakes added. The domestic Tianhua Chemical Machinery Research Institute is based on high-temperature and corrosion-resistant resin, and the large flake solid graphite flakes use strong electrostatic conductivity as the main aggregate, with high body strength and good wear resistance.

Chopped fiber material with good resistance to deformation and cracking is a solvent-free thick film conductive coating containing functional fillers. The coating has anti-corrosion medium penetration, low curing residual stress, strong resistance to matrix deformation, crack resistance, stable construction performance, and long-term conductivity. It can be used as an electrostatic conductive coating for the inner wall of crude oil storage tanks. According to reports, electroless plating technology is used to coat graphite powder with metals such as copper, nickel, and silver to prepare composite conductive fillers. The amount used in conductive coatings is 30%, which not only has good electrical conductivity, but also has further corrosion resistance. . improve.
