1)Product introduction
Natural flake graphite is also known as natural graphite, flake graphite, crystalline graphite and graphite powder. The natural flake graphite operated by Hunan Xintan is natural eutectic stone ink, which is similar in shape to fish scale and belongs to a hexahedral crystal system with a layered structure. It is purified from graphite by chemical process. According to the different carbon content, it can be divided into medium carbon graphite, high carbon graphite and high purity graphite. Particle size can be processed into 50 mesh, 80 mesh, 100 mesh 200 mesh, 325 mesh and other different specifications of products according to customer needs. Natural flake graphite has crystalline integrity, film property, toughness, floatability, lubricity and plasticity. It can be used for carbon brush, pencil lead, grease, seed lubricant, seals, mold coating, brake pads, refractory materials, batteries and so on. Natural flake graphite has excellent physical and chemical properties, in recent years with the continuous development of science and technology, more and more customers use natural flake graphite as lead battery plate, lithium battery positive and negative conductive agent, nickel-metal hydride, nickel-cadmium battery, light-sensitive battery, and graphite in the atomic energy industry and national defense industry have a wide range of uses.
According to the different fixed carbon content, flake graphite can be divided into high purity graphite, high carbon graphite, medium carbon graphite, low carbon graphite, different carbon content flake graphite can manufacture different products.
