Flake graphite is a natural crystalline graphite in the shape of fish phosphorus. It belongs to the hexagonal crystal system and has a layered structure. Natural flake graphite is formed from carbon materials under high temperatures and high pressure and exists in the form of flakes or plates. It has excellent properties such as high-temperature resistance, radiation resistance, electrical conductivity, and self-lubrication. There are many sizes that can be ground and processed. Such as -100 mesh, +100 mesh, and +50 mesh.
It is a form of naturally occurring crystalline carbon renowned for its distinctive flaky morphology and remarkable properties. Sourced directly from select graphite mine and subjected to rigorous purification and processing for particle size, this graphite variant stands out for its electrical and thermal conductivity, high-temperature resistance, and chemical inertness.
Natural Flake Graphite Unique Properties
It is classified by carbon content; for example, 99.9% C% is high-purity graphite; 94% C% < 99% is high-carbon graphite; 80% C% < 94% is medium-carbon graphite; 50% C% < 80% is low-carbon graphite.
The conductivity of flake graphite has long been used in industry, and carbon anode materials play an oxidative role in batteries in the материал катода industry. Lubricating performance is also better; the more significant the scale, the smaller the coefficient of friction. Flake graphite is a super material in the chemical industry.
В производстве он используется для смазки различных искусств, в том числе шестерен, подшипников, скольжения других движущихся частей. Это уменьшает трение и повышает эффективность работы машины. Он также выступает в качестве смазки для паровых двигателей и двигателей внутреннего сгорания.
Another use is manufacturing metal smelting crucibles and various refractory products for metallurgical печи. It is the main raw material for making brushes and mechanical carbon, and can also be used to produce graphite electrodes.
