effect of extended ball milling of graphite

Effect of extended ball milling on graphite ScienceDirect

03/02/2003· Ball milling of graphite for up to 1000 h in vacuum lead to the formation of a highly reactive carbon which was found to chemisorb large amounts of carbon dioxide after exposure to air. The presence of CO 2 on the surface was confirmed by FTIR and its removal during heating was demonstrated by TG–FTIR and FTIR of heated powders. The chemisorption was incomplete even

Effect of extended ball milling on graphite ScienceDirect

Graphite has been milled for up to 1000 h in a laboratory scale tumbling ball mill under vacuum. Raman spectroscopy of the powders indicated the increasing dominance of D-type graphitic sp 2 bonding over G-type bonding with increasing milling time. Diamond-like sp 3 bonding and possibly fullerene-like bonding also became evident after milling. TEM of the 100 h sample showed the presence of ribbons

Effect of ball milling in presence of additives (Graphite

Effect of ball milling in presence of additives (Graphite, AlCl3, effects of both graphite and AlCl 3 were investigated. It has been established that increasing ball milling time up to 5h is necessary to activate the intermetallic and to decrease sufficiently its crystallites and particles size. On one hand, the presence of AlCl 3 provides the best hydrolysis performance (14 % of the

Effect of Heating Temperature of Expandable Graphite on

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
