Impervious Graphite Grades in Process Equipment

Most graphite applications are designed with a particular graphite grade in mind. Impervious graphite grades, where the original material is altered to eliminate porosity, are especially in demand for some common graphite applications. Graphite process equipment, especially heat exchangers, are increasingly being used in chemical processing, as well as pharmaceutical and other process applications requiring high corrosion resistance. Graphite Applications in Heat Exchangers Any graphite grade has great thermal conductivity that makes it suitable for the construction of heat exchangers and other process equipment. These systems transfer heat between a substance and a fluid, many of which are corrosive. Not...

Industrial Uses of Graphite in the Clean Energy Field

Industrial uses of graphite in the field of renewable energy are well-known. Batteries that store clean energy when the sun sets and the wind dies down rely on graphite components. A fast-growing sector of the graphite market is providing components for solar and wind industries, as well as to battery manufacturers. Electrification is the direction most governments and private entities are adopting in pursuit of the green, renewable power source of the future. However, there are other green industrial uses of graphite. We will explore one in particular here -- hydrogen fuel cells. This technology, which has been around for...
