Ball-milling preparation of titanium/graphene

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.

Optimization of ball milling parameters to produce

2013-11-11  Ball milling is a common mechanical process to produce superfine powders. In this research, a planetary ball mill was chosen as a grinding tool due to its simplicity. The sieved powder was first mixed with Pluronic F127 and milled at different mass concentrations (0.4%, 1.2%, 2.0%, and 2.8% ( w / v )) at a constant milling time (4 h) and fixed bead amount (25 g).
