    The top down approach is an alternative method for large scale and low cost of production. For instance, high energy ball milling is a top down method using planetary ball mills. To obtain optimized milling parameters in a planetary ball mill, many trials are needed.Apr 17, 2018 In general, after 8 h ball milled, the ball milling level is appropriate. The Ti 3 C 2 slurry after 8 h ball milled was stable at room temperature for around 3 h and in the refrigerator for 6–8 h. It can be concluded that the ball milling can obviously reduce the particle size of the Ti 3 C 2 slurry to improve its stability. In this.
