Graphite Grades - Properties of Graphite Materials

The fine grain graphite grades are typically available in smaller cross sections than the medium grain graphite grades. This is because fine grain graphite grades are very dense and highly engineered products. To maintain the material properties and design characteristics these materials are processed in smaller cross sectional blocks.

Graphite: The mineral Graphite information and pictures

Graphite is a mineral composed exclusively of the element carbon. Graphite has the same chemical composition as Diamond, which is also pure carbon, but the molecular structure of Graphite and Diamond is entirely different. This causes almost opposite characteristics in their physical properties.
