Flake graphite is a kind of natural graphite. After being mined and purified, the general shape is fish scale shape, so it is called flake graphite. Expandable graphite is flake graphite that has been pickled and intercalated to expand about 300 times compared to the previous graphite, and can be used as coil and flexible graphite raw materials. The following editor will give you a detailed introduction to the difference between flake graphite and expandable graphite:
1. The use of flake graphite is more extensive than that of expandable graphite
In industrial production, in addition to the function of expandable graphite, flake graphite has much better electrical conductivity, thermal conductivity, smoothness, etc. than expandable graphite, so it is more widely used in industrial practice.
2. The production process of flake graphite and expandable graphite is different
Flake graphite is mainly made by mechanical damage and grinding, while expandable graphite is mainly made by chemical acid liquid impregnation and other processing methods. The production process is more complicated than flake graphite.
3. The particle size of flake graphite is smaller than that of expandable graphite
The particle size of flake graphite is generally smaller, and the particle size of expandable graphite is relatively coarse. Because of the expansion function of expandable graphite, the coarse particle size easily promotes the expansion of graphite, so the particle size of expandable graphite is coarser.
