Note:
Distinctions should be made between coarse particulate carbon or
granular carbon
(larger than about

but smaller than about
in average size), fine particulate carbon or powder or flour (between
and
in average size) and
colloidal carbon
(below approximately
in size in at least one direction), e.g. carbon blacks and colloidal carbon.
