May 21, 2020 The results show that the high-energy ball milling cannot effectively reduce the particle size of mixed powder with short milling time. In addition, the particle size of the mixed powder is significantly reduced, while the specific surface area is significantly increased when the ball milling time exceeds 25 hours.
High-energy ball milling is a simple, effective and productive way to produce various nano-crystal powders in high-energy planetary ball mills 7. High reactivity and small particle size can facilitate the production of high- density ceramics at low sintering temperatures 8. Therefore, the SPS along with high-energy ball milling has

Ball-milling has been used to prepare performing CO tolerant polymer electrolyte fuel cell anode catalysts that contain Pt and Ru. The catalyst precursors are obtained by milling together Pt, Ru and a dispersing agent in the atomic ratio 0.5, 0.5 and 4.0. This precursor is not easily recovered after milling because it sticks to the walls of the vial and on the grinding balls. However, the ...
