About Graphite

Graphite is an allotrope of Carbon. It is found naturally in veins in rocks and always contains some impurities. It comes in two forms; foliated and amorphous. Foliated Graphite is infusible, a good conductor of heat and electricity, is resistant to acids and alkalies and is readily moulded. Amorphous Graphite occurs as fine particles and is the result of thermal metamorphism of coal – the last stage of coalification. Crystalline Graphite or Flake Granite contain a high Graphite content and occur as flat, plate-like hexagonal particles.

Graphite is often purified at high temperatures to free it of Silicon, Calcium, Aluminium and Manganese and treated with a freon gas to eliminate Boron and Vanadium.

Uses

Graphite is commonly used as a lubricant, as “lead” in pencils, batteries, steelmaking, brake linings, foundry facings, and by refractories.
