Chinese Amorphous Graphite

Also known as aphanitic graphite powder, the main term amorphous is a misnomer, since all graphite is crystalline. A better term for this type of fine-grained black graphite is microcrystalline, usually defined as being finer than 40µm in diameter, which is the low limit of resolution of the human eye. Some microcrystalline structure can be tough to see even under a microscope.

Our company specializes in manufacturing natural microcrystalline graphite with carbon contents as high as 90%, while retaining its properties of high temperature resistance, acid, alkali & oxidation resistance, lubricating properties, and high thermal & electrical conductivity.

Amorphous graphite is widely used in the refractories industry to manufacture crucibles, ladles, molds, etc., steel casting, and graphite electrodes used in many metallurgical furnaces, including the electric arc furnaces used in steel processing. Secondary uses include: brake linings, gaskets and clutch materials, foundry facing mold wash, and even pencil lead.

Primary mesh sizes available: +80, -100, -150, -200 and -325.

Customization is available upon request.
