Wat is keunstmjittich grafyt ?

(Wat is keunstmjittich grafyt ?)

Yn in brede sin, alle grafytmaterialen krigen troch organyske karbonisaasje en dêrnei grafitisaasje by hege temperatuer kin keunstmjittich grafyt neamd wurde, lykas koalstoffiber, pyrolytyske koalstof, foamed graphite, ensfh. In the narrow sense, artificial graphite usually refers to the block solid material obtained through the processes of batching, kneading, moulding, carbonization and graphitization, using carbonaceous raw materials with low impurity content as aggregates, stienkoal teer pitch, ensfh. as binders. Such as graphite electrodes, isostatic graphite, ensfh.

What is Production method of Artificial graphite ?

There are many ways to manufacture artificial graphite. The common method is to use powdered high-quality calcined petroleum coke as the main raw material, add asphalt as a binder, en foegje dan in lyts bedrach fan oare helpstoffen ta. After the various raw materials are combined, se wurde yn foarm drukt, and then treated in a non-oxidizing atmosphere at 2500-3000 ° C to make them graphitized.

What is the main characteristics of Artificial graphite ?

Crystal structure

Natuerlik grafyt: The crystal development is relatively complete, the degree of graphitization of flake graphite is more than 98%, and the degree of graphitization of natural microcrystalline graphite is usually below 93%.

Keunstmjittich grafyt: The degree of crystal development depends on the raw material and the heat treatment temperature. Algemien sprutsen, wat heger de waarmte behanneling temperatuer, the higher the degree of graphitization. The degree of graphitization of industrially produced artificial graphite is usually less than 90%.

organizational structure

Natuerlike flake grafyt: It is a single crystal with a relatively simple structure and only has crystallographic defects (such as point defects, dislocations, stacking faults, ensfh.), and exhibits anisotropic characteristics on the macroscopic level. The grains of natural microcrystalline graphite are small, the grains are disorderly arranged, and there are pores after removal of impurities, which shows isotropy on the macroscopic level.

Keunstmjittich grafyt: It can be regarded as a multi-phase material, including graphite phase transformed from carbonaceous particles such as petroleum coke or pitch coke, graphite phase transformed from coal tar binder surrounding the particles, particle accumulation or coal tar pitch. The pores formed by the binder after heat treatment, ensfh.

physical form Natural graphite: usually exists in the form of powder and can be used alone, but it is usually used in combination with other materials.

Keunstmjittich grafyt: There are many forms, ynklusyf poeder, fiber and block, while artificial graphite in the narrow sense is usually block, which needs to be processed into a certain shape when used.
