2017-7-1  The results show that the combined application of ball grinding (at 400 rpm) and AlCl 3 (0.5 wt%) could give the highest bleaching efficiency, wherein the Fe 2 O 3 content decreased from 1.34% to 0.76% for Beihai kaolin, and 2.05% to 1.42% for Xingzi kaolin, corresponding to an increase of 4.98 and 12.12 percentage points, respectively. The values are acceptable in the ceramics industry.
