2018-10-11 Ti powders with a purity of 99.9% and the as-prepared GE were used as raw materials for the following ball-milling treatment to prepare Ti/GE composites. All the samples were ball-milled using a planetary ball mill (pulverisette 7 plus, FRITSCH) in a ZrO 2 vessel under an Ar atmosphere at a ball-milling speed of 600 rpm for 10 h. The ball-to-powder weight ratio was 15:1.

2021-2-1 Garnet-type solid electrolytes, such as Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 (LLZTO), are promising materials for solid-state batteries, but processing remains a challenge, in part due to the high sintering temperature required for densification. This temperature can be lowered by decreasing the initial particle size via solvent-assisted ball milling, but the relationship between solvent choice

2013-11-11 Ball milling is a common method in the size reduction of material. The milling process produces nanopowders through the impact forces generated by action of centrifugal forces. Milling parameters such as milling time, mass concentration, and bead amount are important parameters that need to be considered in producing superfine powders.
