Expandable Graphite

Expandable graphite, also known as graphite acid or graphite oxide, is a graphite inter layer compound prepared by using chemical oxidation (chemical method), microwave method, explosion method for natural flake graphite treatment. After special treatment, expandable graphite can be instantly expanded into worm-like shape under high temperature.

Different types of insert lead to different structures, giving it unique physical and chemical properties such as high electrical and thermal conductivity, superconductivity, magnetic permeability, battery performance, catalytic properties, and expansion performance. The application of expandable graphite covers the practical use in high-conductivity materials, battery materials, efficient catalysts, hydrogen storage materials, and improvements in expansible graphite sealing materials.
