Graphitization carbon
WebAug 28, 2014 · Interestingly, the amount of graphitization does not appear to diminish with a substantial decrease in iron content. Fig. 3a shows that a reduction of the iron concentration to 10% of the original value results in broader Fe 3 C peaks of much lower intensity but with the graphite peak intensity maintained. This is more clearly shown in a … WebJan 1, 2016 · The effect of a graphitization treatment on the phyisico-chemical properties of an activated carbon have been studied by means of multi-technical approach.
