Graphite Powder, Natural & Synthetic,

Physical Properties

Many different standard granulations are available between 5 mesh USS and 0.7 microns.

Chemical Properties

The various graphite grade typical purities are: Amorphous= 84.0%, Crystalline flake= 87.8% to 95.6%, Crystalline vein= 98.0%, Primary artificial/synthetic= 99.9%, Secondary artificial/synthetic= 99.6% and Calcined petroleum coke= 99.7%

Typical Applications

The primary uses 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.

Natural graphite has found uses as the marking material ("lead") in common pencils, in zinc-carbon batteries, in electric motor brushes, and various specialized applications.

A new application for nuclear grade graphite is in Very High Temperature Reactors (VHTR) and the Next Generation Nuclear Plant (NGNP).
