Therefore, it is not suitable as filler coke for polygranular graphite products and is also less suitable for polycrystalline carbon products. Because of its isotropy it is less suitable to produce an anisotropic synthetic graphite. All coke contain a fraction of matter that can be released as volatiles during heat treatment. This mass fraction, the so-called volatile matter, is in the case of fluid coke about 6 wt.%."},"links":[{"term":"carbonization","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/C00840"},{"term":"coke","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/C01142"},{"term":"coking","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/C01144"},{"term":"delayed coke","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/D01577"},{"term":"filler coke","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/F02364"},{"term":"mass fraction","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/M03722"},{"term":"polygranular graphite","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/P04731"},{"term":"synthetic graphite","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/S06233"}],"sources":["PAC, 1995, 67, 473.
