WebApr 6, 2024 · Here the graphite was placed on top of the CB, covering it completely. It is noteworthy that after a weight loss identical to the CB proportion, the reaction almost comes to an end, as shown by the flattening observed in the thermograms. This indicates that predominantly CB reacts under the selected conditions.
