04433 IUPAC Gold Book - particulate carbon 10.1351/goldbook.P04433 P04433 current 1 A carbon material consisting of separated monolithic particles. Distinctions should be made between coarse particulate carbon or granular carbon (larger than about \(100\ \unicode[Times]{x3BC}\rm{m}\), but smaller than about \(1\ \rm{cm}\) in average size), fine particulate carbon or powder or flour (between \(1\) and \(100\ \unicode[Times]{x3BC}\rm{m}\) in average size) and colloidal carbon (below approximately \(1\ \unicode[Times]{x3BC}\rm{m}\) in size in at least one direction), e.g. carbon blacks and colloidal carbon. carbon blacks https://goldbook.iupac.org//terms/view/C00824 carbon material https://goldbook.iupac.org//terms/view/C00841 colloidal carbon https://goldbook.iupac.org//terms/view/C01173 granular carbon https://goldbook.iupac.org//terms/view/G02682 PAC, 1995, 67, 473.
