Within graphite powders, one can distinguish two main families based on the origin: natural and synthetic graphite (see Fig. 1). Fig. 1 Main steps of the synthetic and natural graphite manufacturing process. Natural graphite results from the transformation of organic matter deposits subjected to strong pressures combined with high temperatures over millions of years.
