Mechanical treatment of kaolins was carried out in a Planetary Micro Mill. The samples, (m = 7.5–10 g), were ground in a water suspension, using different sizes of ZrO 2 balls and the necessary grinding time, in order to produce samples with d 50 of 0.5 μm, approximately. Details of the grinding conditions are listed in Table 2.The fineness …Web
