Synthetic Graphite and Its Various Grades

Here’s a question: What do electric discharge machines, degassing systems, and li-ion batteries all have in common? Yep, synthetic graphite. Ok, so that was easy, but extra points if you added to that list on your own things like nuclear graphite, anode material, and a million other products and machine components that require various grades of synthetic graphite to function properly. Synthetic graphite is classified into different grades based on its characteristics, properties, and intended applications. Synthetic graphite grades used in electric discharge machines will differ from synthetic graphite grades used in degassing systems. These grades are designed to meet...

Beyond Lithium Ion Batteries--Dangers to Graphite in High Heat Environments

Synthetic graphite is a carbon material that is manufactured through the high-temperature treatment of carbon precursors, often petroleum-based materials or coal tar pitch. It is used as the anode material in lithium ion batteries, as crucibles in foundries, and many other applications in between. Synthetic graphite oxidation refers to the process by which synthetic graphite materials react with oxygen in the presence of heat, such as when graphite is used in the steelmaking process. Oxidation leads to the formation of various oxidation products which can degrade properties of graphite that make it such an attractive material in the first place....
