At the optimal hydration time of 10 s, the whisker length was 309 μm, which was 25% lower than the maximum length without ball milling. Furthermore, the whisker length distribution graph exhibited a distinct shift to the left. These results indicate that the ball-milling treatment suppressed the whisker length of CSWs prepared from crystal seeds.
