granular carbon
The term granular carbon is equivalent to coarse @[email protected] This is a @[email protected] consisting of separate particles or grains which are monolithic, on the average larger than about \(100\ \unicode[Times]{x3BC}\text{m}\) in diameter, but smaller than about \(1\ \text{cm}\).
Although limits of size cannot be exactly defined, @[email protected] grains obtained by grinding belong to coarse @[email protected] for grain sizes above ca. \(100\ \unicode[Times]{x3BC}\text{m}\), or to fine @[email protected] for grain sizes below ca. \(100\ \unicode[Times]{x3BC}\text{m}\). @[email protected] @[email protected] obtained by grinding of @[email protected] is a typical extra fine @[email protected] Industrial carbon materials (such as electrodes) are made with @[email protected] composed of coarse @[email protected] (@[email protected] grains) and fine @[email protected] (flour), and sometimes even @[email protected], @[email protected] or @[email protected]). They are therefore polygranular materials.
