The family of graphite materials includes natural graphite types, such as amorphous Graphite, crystalline flake and vein graphites, synthetic (artificial) Graphite, and various purified or treated graphitic products. These materials are sourced from selected and qualified mines and sources from around the world or are produced or treated in various, unique ways, including Electro-Thermal Treatment/Purification Technology created by Superior Graphite. The various forms of Graphite are as follows: Amorphous Graphite: This variety is typically formed by the metamorphism of coal beds or carbon-rich sediments associated with igneous activity. It is generally a soft, darker black-colored graphite, less reflective than other varieties of natural crystalline Graphite. Commonly found as "microcrystalline" particles, this variety of Graphite has a lower graphitic carbon level when compared to other naturally occurring crystalline graphite varieties and is typically formed as flat plate–like particles; this variety of Graphite is disseminated throughout layers of metamorphic rock; either in isolated pockets or more broadly distributed throughout the parent rock matrix. Generally very brilliant in color, the size and thickness of the individual flakes can vary depending on the ore deposit. Unlike other varieties of natural crystalline Graphite, flake needs to be mechanically/chemically processed or "upgraded" to reach the necessary carbon levels for industrial applications. This variety of Graphite is typically found in fractures or fissures associated with metamorphic and igneous formations, hypothesized as being deposited in the vapor or fluid state. Generally, a soft, very brilliant variety of natural crystalline Graphite exhibits one of the highest degrees of crystallinity and, in some formations, the most pure form of the natural crystalline Graphite found. The vein can range from finer, needle–like grain to a more coarse massive lump.
