Product Description

     Graphite Electrode is a kind of high temperature resistant graphite conductive material, which is made of petroleum coke and pitch coke as aggregate and coal tar pitch as binder through calcination, crushing and grinding of raw materials, proportioning, kneading, moulding, roasting, impregnation, graphitization and mechanical processing. It is called artificial graphite electrode (abbreviated as graphite electrode). Natural graphite electrode prepared from natural graphite as raw material

(1) for arc steelmaking furnaces

(2) used in ore smelting electric furnace

(3) used in resistance furnace

(4) for preparing special shaped graphite products.

Features:
At room temperature, the chemical properties of elemental carbon are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents; it reacts with oxygen at different temperatures to produce carbon dioxide or carbon monoxide; only fluorine can react directly with elemental carbon in halogen; under heating, elemental carbon is more easily oxidized by acid; at high temperature, carbon can also react with many other substances. Metals react to form metal carbides. Carbon is reducible and can be smelted at high temperatures.

Graphite is a crystalline mineral of carbonaceous elements. Its crystal lattice is hexagonal layered structure. The distance between each network layer is 340pm, and the spacing of carbon atoms in the same network layer is 142pm. It belongs to six square crystal system with complete lamellar cleavage. The cleavage surface is mainly composed of molecular bonds, and its attraction to molecules is weak, so its natural floatability is very good.

Graphite, diamond, carbon 60 and carbon nanotubes are the elements of carbon, and they are allotropic to each other.
