The difference between colloidal graphite and flake graphite

   Flake graphite refers to the raw ore of natural graphite. After the intercalation treatment of nitric acid and drying, the expanded graphite is obtained. Nano-graphite powder is a refined subdivision of flake graphite.

   The dispersion system of colloidal graphite particles with a diameter of 1 nm to 100 nm is called colloid. Colloidal graphite is a nanomaterial. Graphite is an allotrope of the element carbon. Each carbon atom is surrounded by three other carbon atoms (hexagons arranged in a honeycomb), which are covalently bonded to form a covalent molecule.

   Since each carbon atom emits an electron, graphite is a conductor. Uses of graphite include pencil leads and lubricants. Carbon is a non-metallic element. The Latin word Carbonium means "coal, charcoal". The Chinese character "Char" consists of the characters "Char" and "Stone".
