Description




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 conditions, the melting point of 3000 or more, is one of the most resistant minerals. It can be conductive, heat conduction.

    Flake Graphite!


Graphite crystals are scaly; this is made of high-intensity pressure deterioration. This kind of graphite ore is one of the best minerals in nature, and it can obtain high grade graphite concentrate after multi-grinding. This kind of graphite floatability, lubricity, plasticity than other types of graphite superior; so its industrial value is the largest.


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.
