Graphite!naturally-occurring Form Of Crystalline Carbon

Graphite ,soft, dark gray; greasy feeling, can contaminate the paper. Hardness of 1 to 2, along the vertical direction ,with the increase of its impurity, its hardness can be increased to 3 to 5. Specific gravity of 1.9 to 2.3. Specific surface area range of 1-20m / g, in the isolated oxygen...

Description




Graphite is a naturally-occurring form of crystalline carbon. It is a native element mineral found in metamorphic and igneous rocks. Graphite is a mineral of extremes.

 

Chemical nature of graphite is not active, corrosion resistance, and it is difficult to react with acid, alkali and others. Heat in the air or oxygen, can burn and generate carbon dioxide. Strong oxidizing agent will oxidize it into organic acid, it also was used as anti-friction agent and lubricating material, making crucible, electrode, dry battery, pencil lead.

    Flake Graphite!


Graphite crystals are scaly; this is made under high-intensity pressure deterioration. This kind of graphite is one of the best minerals in the nature,and it can obtain high grade graphite concentrate after multi-grinding.

As anti-corrosion materials, flake graphite and carbon black, talcum powder and oil made of rust-proof primer, with good resistance to chemical and solvent corrosion performance; if the formula by adding zinc and other chemical pigments, the anti-rust effect will be better.

Expandable Graphite!


Expanded graphite, known as expandable graphite or graphite worms, from the original scales into a very low density worm-like, forming a very good insulation layer. Expanded graphite is both a carbon source in the expansion system and a thermal insulation layer. It is effective in heat insulation. It has the characteristics of low heat release rate, low mass loss and little smoke.
