WebJan 3, 2009 · Cryptocrystalline graphite in composite nodules displays the Raman features of highly ordered graphite, that is, small or absent D 1 peak and sharp G band (Fig. 4 b). The average values for R 1 and R 2 are 0.09 and 0.05, respectively. Such values agree with in-plane crystallite sizes larger than 2,000 Å. 2. WebIn this study, cryptocrystalline graphite (CG) was investigated as a novel functional filler for acrylonitrile-butadiene rubber (NBR)/carbon black (CB) composites. NBR/CB/CG composites are characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) as well as differential scanning calorimetry (DSC). WebAmorphous graphite also call cryptocrystalline graphite. This ore have small graphite crystal, surface is earthy and industrial performance is not good. But this graphite ore have high grade, general 60-80%. But its flotability is bad. After flotation, the grade have no remarkable increase. Thus, if the grade is lower than 65%, shall not be ... church uk retail limited
