In the present study, high-energy ball-milling technique was applied to barium dititanate (BaTi2O5) powders. The improvement in sinterability of the ball-milled powders was evidenced, as compared with the sintering behavior of unmilled powders. After ball-milling, BaTi2O5 coarse powders were effectively ground into fine ones, whose maximum particle size was decreased from ~400 to ~40 …

A detailed investigation of planetary ball‐milling for coarsened AlON powder was carried out. Our results showed that the weight ratios of milling ball‐to‐powder, the revolution rate and the planetary ball‐milling time have significant impacts on the microscopic morphology, particle size distribution and average particle size of powder.

In this paper, the milling parameters of high energy ball mill (Fritsch Pulverisette 7) like vial geometry, number and size of balls and speed of the mill were modelled and discussed. Simulations through discrete element method (DEM) provide correlation between the milling parameters. A mathematical model is used to improve and develop this process.
