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 (99.5−99.9%). Primary grade synthetic graphite can approach the good lubricity of quality natural graphite. Natural graphite is derived from mining.
The resulting synthetic graphite is highly pure—in excess of 99.9% C purity—but typically has lower density, conductivity and a higher porosity than its natural equivalent. [7] Synthetic graphite can be formed into very large (centimeter-scale) flakes while maintaining its high purity, unlike almost all sources of natural graphite. [7]
A lubricant (sometimes shortened to lube) is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces.
A sample of synthetic motor oil. Synthetic oil is a lubricant consisting of chemical compounds that are artificially modified or synthesised. Synthetic oil is used as a substitute for petroleum-refined oils when operating in extreme temperature, in metal stamping to provide environmental and other benefits, and to lubricate pendulum clocks.
Graphite, named by Abraham Gottlob Werner in 1789, from the Greek γράφειν (graphein, "to draw/write", for its use in pencils) is one of the most common allotropes of carbon. Unlike diamond, graphite is an electrical conductor. Thus, it can be used in, for instance, electrical arc lamp electrodes.
At full capacity, the new facility is expected to produce approximately 31,500 tonnes per annum (“tpa”) of synthetic graphite, which can support the production of lithium-ion batteries for approximately 325,000 EVs each year. China currently has over 95% market share for battery grade graphite 1. The new facility is expected to reach full ...
