isotropic carbon

https://doi.org/10.1351/goldbook.I03354
A monolithic
carbon material
without preferred crystallographic orientation of the microstructure.
Note:
Isotropic
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
are
isotropic
at the crystalline (sub-grain) level.
