Sri Lanka graphite (also known as Vein Graphite) is a naturally occurring form of pyrolitic carbon (solid carbon deposited from a fluid phase). Vein graphite has a morphology that ranges from flake-like for fine particles, needle or acicular for medium sized particles, and grains or lumps for very coarse particles.
Range in size from 1-150 cm ” material is available in sizes ranging from fine powder to 10 cm lumps.
Sri Lanka graphite has the highest degree of crystalline of all conventional graphite materials. Vein graphite used in electrical applications. Many of the highest quality electrical motor brushes and other current carrying applications.
In friction applications it is used in advanced brake and clutch applications. Other applications utilize flake graphite. Commercial grades are available in purities ranging from 80-99% carbon, and sizes from 3-micrometer powder to 8-10 cm lumps.
