Expanded graphite is made by acidizing the intercalation of flake graphite in a mixture of concentrated sulfuric acid and strong oxidant. Tianshengda graphite small make up today for you to explain the relationship between expanded graphite and the properties of flake graphite:

1. Expanded graphite has excellent properties of flake graphite.

Although the macroscopic and microscopic structures of expanded graphite and natural flake graphite are quite different, the lattice constants measured by X-ray diffractometer are no different from those of flake graphite and acid-treated graphite. This suggests that, like natural flake graphite, they are hexagonal layered crystals.

Although each of the curled flat layers of expanded graphite has a certain thickness, they are still made up of graphite microcrystals. So the expanded graphite kept many excellent properties of natural flake graphite.

2. Expanded graphite also has new skills that flake graphite does not have.

From the perspective of the formation mechanism of expanded graphite, in addition to the formation of edge compounds, interlayer compounds were also generated, which increased the graphite layer spacing and resulted in significant differences in microstructure, resulting in differences in physical and chemical properties between expanded graphite and flake graphite.

Flake graphite and expanded graphite are the main products of Tianshengda graphite Co.,Ltd,. We have been developing in the graphite industry for more than ten years, and now we have accumulated mature experience and excellent technology. We welcome customers who need to purchase in this aspect to come to the factory and communicate with us.
