Graphite is the mineral form of carbon. Veins of graphite occur in limestone due the presence of organic materials. Graphite is a soft mineral and occurs in either lump or flake form. Graphite is the only non-metal element that is a good conductor of electricity. Crystal structures rarely occur and easily break down. This is the reason for the material’s greasy feeling despite being a dry lubricant.
