A monolithic carbon material
without preferred crystallographic orientation of the microstructure.
carbon can also be a graphite material
. The isotropy can be gross (bulk), macroscopic or microscopic, depending on the structural
level at which isotropy is obtained. This word is widely used today and its meaning
covers all the above levels. For example, the aerospace graphites have isotropy built
in by random grain orientation. Some nuclear graphites
at the crystalline (sub-grain) level.
