Natural Graphite Spherical Powder
Graphite, known archaically as Plumbago, is a crystalline allotrope of carbon, a semimetal, a native mineral element, and a carbon form. Graphite is the most stable form of carbon under standard conditions. Therefore, it is used in thermochemistry as a standard state to define the heat of carbon compound formation.
The main types of natural graphite, each in different types of mineral deposits are:
Small flakes of crystalline graphite (or flake graphite) appear as flat, isolated and flat particles, with hexagonal edges if they do not break. When they break, the edges can be irregular or angular;
Amorphous graphite: very fine lamellar graphite is sometimes called amorphous;
The graphite (or venous graphite) appears in the fractures of the veins or fissures and is presented as a massive platinum growth of fibrous or acicular crystalline aggregates, and is probably of hydrothermal origin.
Highly ordered pyrolytic graphite refers to graphite with an angular dispersion between the graphite sheets of less than 1 °.
The name “graphite fiber” is sometimes used to refer to carbon fibers or carbon fiber-reinforced polymers.
