Natural flake graphite powder is a natural crystalline graphite, which is in the shape of fish phosphorus. It belongs to hexagonal crystal system with layered structure. It has good properties of high temperature resistance, electrical conductivity, heat conduction, lubrication, plasticity, acid and alkali resistance.
Expanded graphite has good corrosion resistance, high and low temperature resistance, good compression resilience and high strength. Expanded graphite is very easy to absorb oil, organic molecules and hydrophobic substances. After oil absorption, it floats on the water surface, which is easy to catch and recycle, can be reused and easy to handle.
