Graphite: what every resource investor needs to know

Vein graphite is a naturally occurring pyrolytic carbon. This form of graphite is deposited as solid graphite directly from a fluid phase, creating an extremely high degree of crystallinity. Vein graphite is utilized extensively in formed graphite products for electrical applications. High-quality electrical motor brushes and other current-carrying carbons are based on formulations using vein graphite. It is also used in friction applications, such as advanced brake and clutch formulations, as well as most applications that utilize flake graphite. Vein graphite is also the type of graphite used in pebble-bed nuclear reactors. Vein graphite is 90% to 96% carbon and is most valuable because it requires the least processing to achieve ultra high purity.
