Graphite powder is a widely used industrial material, which is obtained from high-purity graphite after crushing, grinding, and screening. The classification of graphite powder is mainly based on the particle size, ranging from 50 mesh to 30000 mesh. The larger the mesh, the finer the particle size, and the higher the price.
Request a quotePure natural graphite powder and artificial graphite powder are widely used in terms of price, performance, and materials. Although they are used in industrial production, they have prominent differences.
Material differences
Natural flake graphite can be made into lithium cells by rough processing and graphite sheet by fine processing. Artificial graphite carbonizes the insulating layer sheet, and then adds graphite powder on both sides, which has a higher cost and relatively less output.
Differences in performance
Although most of them are used on tablets and smartphones. However, due to the price advantages of pure natural flake graphite, it is mostly used in low-end intelligent machines.
Differences in the crystal structure
Natural graphite: the crystal development is relatively perfect, the graphitization degree of flake graphite is more than 98%, while the graphitization degree of natural microcrystalline graphite is usually less than 93%. Artificial graphite: the degree of crystal development depends on the raw material and heat treatment temperature. Generally speaking, the higher the heat treatment temperature, the higher the degree of graphitization. At present, the graphitization degree of artificial graphite produced in the industry is usually less than 90%.
Differences in physical form Differences in physical form Differences in physical form
Natural graphite: it usually exists in powder form and can be used alone, but it is usually used after compounding with other materials.
Artificial graphite: there are many forms, including powder, fiber, and block. In the narrow sense, artificial graphite is usually a block, which needs to be processed into a certain shape when used.
Differences in physical and chemical properties
In terms of physical and chemical properties, natural graphite and artificial graphite have both similarities and differences in performance. For example, both natural graphite and artificial graphite are good conductors of heat and electricity, but for graphite powder with the same purity and particle size, natural flake graphite has the best heat transfer and conductivity, followed by natural microcrystalline graphite, and artificial graphite is the lowest. Graphite has good lubricity and certain plasticity. The crystal development of natural flake graphite is relatively perfect, the friction coefficient is small, the lubricity is the best and the plasticity is the highest, followed by dense crystalline graphite and aphanitic graphite, and the artificial graphite is poor.
