Vein graphite
Power Materials
There are three main types of graphite: flake, vein, and amorphous. Vein graphite is believed to originate from crude oil deposits that through time, temperature and pressure were converted to graphite. Vein graphite is currently only mined in Sri Lanka and of the types of graphite it is considered the rarest. Vein graphite is generally used in advanced, thermal and high-friction applications such as car brakes and clutches. However, it is also used in the same way as flake graphite due to it's performance in applications that require high thermal and electrical conductivity.
