Effect of Heating Temperature of Expandable Graphite on Amorphous Process of Expanded Graphite/Ni System during Ball Milling

Abstract:

Two expanded graphites, EG1 and EG2 that were prepared by rapid heating expandable graphite to 600 and 1000 °C, respectively, were ball milled in a high-energy mill under an air atmosphere with 16.7% nickel addition. The X-ray diffraction patterns of the products show that that increasing the heating temperature of expandable graphite accelerates the amorphous process of the EG-Ni systems during the milling process. Ball milling the EG2-Ni mixture results in the formation of an amorphous EG-Ni system and Ni3C phase. Comparing with the amorphous process of the milled EGs without nickel addition, it is concluded that the presence of nickel restrains the process of EG1 in rate, but it promotes this process of EG2.
