Application Range And Requirements Of Crystalline Graphite Powder

wallpapers Industry 2020-06-09

Graphite powder is widely used in metallurgy, chemical industry, machinery, nuclear industry, electronics, aerospace and defence military industry with various characteristics such as high and low-temperature resistance, corrosion resistance, electrical conductivity, thermal conductivity, lubrication, low surface energy, lightweight, and high carbonization yield. Crystalline graphite is affected by factors such as the capacity reduction in the iron and steel industry. The proportion of products used in traditional areas such as refractory and casting has decreased year by year, and the percentage of products used in emerging fields such as new energy and new materials has continued to increase.

The application field of crystalline graphite powder is closely related to its scale characteristics. The large flake graphite in crystalline graphite can be used to prepare expandable graphite. After deep processing such as intercalation, water washing, drying, and high-temperature expansion, expandable graphite not only retains the high-temperature resistance, good electrical and thermal conductivity, plasticity, and chemical properties of natural graphite. Stability and other features, also have the characteristics of softness, resilience and self-adhesion, and can be further applied to flexible graphite (conductive and thermal graphite paper, sealing materials and bipolar plates), stealth materials, environmental protection medical treatment, flame retardant materials and other fields. Large flake graphite can also be used to prepare graphene materials.

Graphene can be widely used in the fields of electronic chips, conductive additives, thermally conductive materials, anticorrosive materials, energy storage materials, biological materials and environmental materials due to its extremely high mechanical strength, thermal conductivity, light transmittance and chemical stability. Fine flake graphite in crystalline graphite is currently mainly used in metallurgical materials, battery materials (fluorinated graphite lithium fluoride batteries, lithium-ion battery anode materials, high-energy battery cathode conductive agents), colloidal graphite and polymer composite materials.
