WebAbout graphitization. Graphitization is a heat treatment process of carbon materials at high temperatures to form graphite structure. By graphitization, electrical conductivity, … WebApr 11, 2024 · The MFCB showed a crystallinity index of 25.8 %, compared to 23.4 % in the case of the TFCB. There is found to be a calculated difference of 2.4 %, which is attributed to the difference in processing conditions. Thus, nitrogen has displayed a critical role in the production of coconut shell chars with better properties.
