2.5.1 Material preparation in a planetary ball mill The iron-coated NbC was prepared separately in a Retsch planetary ball mill prior to mechanical alloying in a stirred media mill. The aim of this step was to grind the feed iron-coated NbC down to finer than 63 µm size. The container of the mill was made of steel and filled with steel balls.

Effect of ball mill speed. Ball mill speed is also a key factor affecting the grinding and cell disruption of SMB samples. A better extraction efficiency may be achieved at a higher speed. Therefore, different ball mill speeds (4 m/s, 4.5 m/s, 5 m/s, 5.5 m/s, 6 m/s) were studied. However, it is found that the ball mill speed in this case had no ...
