英文摘要	To investigate the influence of the ball grinding time on the particle sizes of the negative ion powder and the release ability of negative ions for dental applications. Ethanol as a dispersant, steel ball as grinding media, the negative ion powder was grinded (4h, 8h, 12h, 16h, 22h) through the ultrasonic dispersion and ball milling and high-speed mixing process. Its crystal pattern, particle size and surface morphology were characterized by XRD, dynamic laser scattering instrument, SEM. The number of negative ion in different grinding time was tested by 3010-pro negative ion tester. With the increasing of the milling time, particle size of negative ion powder was gradually decreasing, after 22h, the particle size was 232nm, which was consistent with the results of electron microscope, but the number of negative ions was not significantly changed. Therefore, optimum utilization of the ultrasonic dispersion and ball milling and high-speed mixing technologies is necessary to most efficiently achieve stable dispersions with the target particle size characteristics.
