Preferred Label : granular carbon;
IUPAC definition : The term granular carbon is equivalent to coarse particulate carbon. This is a carbon
material consisting of separate particles or grains which are monolithic, on the average
larger than about 100 µm in diameter, but smaller than about 1 cm.;
Scope note : although limits of size cannot be exactly defined, coke grains obtained by grinding
belong to coarse particulate carbon for grain sizes above ca. 100µm, or to fine particulate
carbon for grain sizes below ca. 100µm. colloidal graphite obtained by grinding of
natural graphite is a typical extra fine particulate carbon. industrial carbon materials
(such as electrodes) are made with fillers composed of coarse particulate carbon (coke
grains) and fine particulate carbon (flour), and sometimes even colloidal carbon,
carbon blacks or soot). they are therefore polygranular materials.;
