Oxygen and Synthetic Graphite: A Corrosive Relationship

Synthetic graphite has been a boon for industry and is the preferred material for a majority of graphite components. It can be produced with many specifications in mind and is thus customizable for use in very extreme conditions. While heat and pressure are often no match for this wonder material, synthetic graphite does have a kryptonite or sorts: oxygen. To be fair, lots of materials don’t particularly like too much oxygen, and synthetic graphite and oxygen don’t always dislike each other. But as we shall see, when things heat up, oxygen can wreak havoc upon synthetic graphite components. Synthetic graphite...

As the Ukrainian people continue to stun the world with their armed and brave resistance to the invasion, we thought this would be an interesting time to explore synthetic graphite’s use in military equipment and weapons. There are, of course, numerous examples where synthetic graphite is used in all the downstream industries that produce components for military equipment, such as in foundries (graphite electrodes) that produce the necessary steel, or in facilities...
