particulate carbon

https://doi.org/10.1351/goldbook.P04433
A
carbon material
consisting of separated monolithic particles.
Note:
Distinctions should be made between coarse particulate carbon or
granular carbon
(larger than about 100 μm, but smaller than about 1 cm in average size), fine particulate carbon or powder or flour (between 1 and 100 μm in average size) and
colloidal carbon
(below approximately 1 μm in size in at least one direction), e.g.
carbon blacks
and
colloidal carbon
.
