Graphite :: MakeItFrom

 · Graphite is a non-oxide engineering ceramic. It has the lowest thermal conductivity among non-oxide engineering ceramics. In addition, it has the lowest tensile strength and a very low density. The graph bars on the material properties cards below compare graphite to other non-oxide engineering ceramics (top) and the entire database (bottom).

Physical Properties

Near absolute zero, graphite has only a few free electrons and acts as an insulator. As temperature rises, electrical conductivity increases. • Good thermal conductivity: outstanding heat transfer properties. • Unique mechanical strength: the tensile, compressive and flexural strength of graphite increases as temperature increases to 2700 K.
