Graphite Micron Powder

Graphite is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure. It occurs naturally in this form and is the most stable form of carbon under standard conditions. It has very high melting point (3600℃) and has a density of 2.25 g/cm3. Graphite micron powders have high structural strength at high temperature, high thermal shock resistance, high thermal conductivity, low thermal expansion, and good chemical resistance. Although graphite is flexible, it is not elastic and has high electrical and thermal conductivity. It is also chemically inert and highly refractory. Since graphite displays low adsorption of X-rays and neutrons, it is very valuable in nuclear applications. Natural graphite powder has found uses as the marking material ("lead") in common pencils, in zinc-carbon batteries, in electric motor brushes, and various specialized applications. The primary uses of graphite powders are making crucibles and other refractory products, lubricants, paint, stove polish, "lead" pencils, electrodes, brake linings, batteries, powder metallurgy, fertilizers, glass manufacture, conductive coatings, and for foundry facings.
