Product Description
Graphite is structurally composed of planes of polycyclic carbon atoms that are hexagonal in orientation. The distance of carbon atoms between planes is longer and therefore the bonding is weaker.
Graphite is best suited for lubrication in air. Water vapor is a necessary component for graphite lubrication. The adsorption of water reduces the bonding energy between the hexagonal planes of the graphite to a lower level than the adhesion energy between a substrate and the graphite. Because water vapor is a requirement for lubrication, graphite is not effective in vacuum. Because it is electrically conductive, graphite can promote galvanic corrosion. In an oxidative atmosphere graphite is effective at high temperatures up to 450° C continuously and can withstand much higher temperature peaks.
Graphite is characterized by two main groups: Natural and synthetic. Synthetic graphite is a high temperature sintered product and is characterized by its high purity of carbon (99.599.9%). The primary grade synthetic graphite can approach the good lubricity of quality natural graphite.
Natural graphite is derived from mining. The quality of natural graphite varies as a result of the ore quality and post mining processing of the ore. The end product is graphite with a content of carbon (high grade graphite 9698% carbon), sulfur, SiO2 and ash. The higher the carbon content and the degree of graphitization (high crystalline) the better the lubricity and resistance to oxidation.
For applications where only a minor lubricity is needed and a more thermally insulating coating is required, then amorphous graphite would be chosen (80% carbon).
