Effects of Ball Size and Particle Size on the Rate of Wet Ball-Milling
Journal of the Ceramic Society of Japan, 1990 A lead-based relaxor material for multilayer ceramic capacitors was ground by ball-milling with partially stabilized zirconia balls of 1, 3 and 15mm in diameter and the effects of ball size and particle size of powder on milling rate were studied. Particle size distribution and specific surface area of powders were examined as a function of grinding ...
