Abstract

When diamond particles are used as abrasive agents, diamond particles have to disperse homogeneously. Consequently, many dispersants are developed to improve the dispersion property of abrasive agents, whereas improvement of surface properties of abrasive agents using dispersant is not essential. We attempted intrinsic surface modification of diamond particles used as abrasive agents by ultrasound exposure. The change of zeta potential by ultrasound exposure was confirmed. Sub-micro diamond particles with average size smaller than 0.3 μm were obtained.
