Preserved Fulltext
Factors of milling rates and contamination due to abrasion of balls were investigated in order to obtain ultrafine powder of pure piezoelectric ceramics. Higher milling rates and lower contamination from balls were obtained for smaller balls. Calcined piezoelectric powders of 1 fJm in mean particle diameter were milled into the fine powders of 0. 2 fJm for about 7 min. It was estimated that milling rates of this case (0. 4mm PSZ balls) was about 10 5 times as that of ball mill (ball size 10
