Graphite facts. Graphite is a non-metallic mineral that has properties similar to metals, such as a good ability to conduct heat and electricity. Graphite occurs naturally or can be produced synthetically. Purified natural graphite has higher crystalline structure and offers better electrical and thermal conductivity than synthetic material.

What is Graphite. Pure graphite is a mineral form of the element carbon (element #6, symbol C). It forms as veins and disseminations in metamorphic rocks as the result of the metamorphism of organic material included in limestone deposits. It is an extremely soft mineral and it breaks into minute, flexible flakes that easily slide over one another.

Synthetic graphite is produced through a complex process of baking petroleum coke at very high temperatures. Synthetic graphite can have a purity of over 99% carbon, and it is used in manufactured products where extremely pure material is required. Graphite is extremely soft, cleaves with very light pressure, and has a very low specific gravity.
