It is low in the ab directions but higher by an order of magnitude in the c direction, as shown in fig.3.12. The increase with temperature is not linear. In the c direction, it increases slowly and gradually. At 0C, the coefficient of thermal expansion averages 2510-6
Carbon Graphite Conductivity Expansion
The Coefficient of Thermal Expansion (CTE) is a measure of the magnitude of this dimensional change. In the design of a Mechanical Seal, Bearing, or other static or dynamic components, it is much easer to accommodate a lower CTE than a higher (some plastics have a 20x higher CTE than carbon graphite
