The increasing of the milling time to T b = 20 h decreased the D 50 value to 0.5 μm, as shown in Fig. 4 (c), and this is attributed to the increase of the fracturing rate. The D 50 value (D 50 = 0.66 μm) of the jet-milled powder at T p = 4 bar is significantly smaller than the D 50 value (D 50 = 3.75 μm) of the unmilled α-Al 2 O 3 powder.
