Preparation of Ultrafine Particles by Nanopowder Process– Factors for Milling Rate and Contamination – [Translated]†
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 μm in mean particle diameter were milled into the fine powders of 0.2 μm for about 7 min. It was estimated that milling rates of this case (0.4 mm PSZ balls) was about 105 times as that of ball mill (ball size 10 mm). Even smaller ultrafine particles of 19 nm in mean particle diameter were obtained by milling for 90 min.† This report was originally printed in Journal of the Japan Society of Powder and Powder Metallurgy, 37(6), 827-831 (1990) in Japanese, before being translated into English by KONA Editorial Committee with the permission of the editorial committee of Japan Society of Powder and Powder Metallurgy.
