The Study on the Preparation of Expanded Graphite by Fine Squama Graphite
The experiment improved the synthetic methods of preparing expanded graphite, using the mixture of H2SO4 and HNO3 as the acid, KMnO4 as oxidizing agent and adopting chemical oxidization method to prepare the expanded graphite under the conditions of different temperature. We can get the optimum conditions of preparing expanded graphite by orthogonal experiment.
