Graphite Cement: A High Temperature-Resistant Building Material

Graphite cement typically refers to a material with adhesive and bonding physical properties that contains graphite as one of its primary components. This is not your typical cement, one of the most ubiquitous, and necessary, building materials used by people today. Your typical cement is made of forms of lime, silica, iron, and aluminum. Like manufactured graphite, cement’s formula can be adjusted to suit specific purposes. One of those materials that can be added to cement to give it certain properties is graphite. Graphite is a form of carbon known for its excellent electrical conductivity, lubricating properties, and high temperature...

Teflon: Not Just for Non-Stick Cookware

Teflon History and ApplicationsGraphite is a high temperature-resistant material. It isn’t too surprising then to find that graphite and Teflon have been combined in industrial applications that go beyond just non-stick cookware, like gasket material (and many others). Teflon-coated graphite refers to a material that consists of a layer of Teflon (a brand name owned by The Chemours Company, for polytetrafluoroethylene, or PTFE) applied to the surface of graphite. This combination offers unique properties and applications, primarily due to the characteristics of both materials. Teflon was a revolutionary invention (or "lucky accident" in the eyes of some!) from it's conception. Roy...

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...
