Abstract
Thirteen oxide powders, all of which are important in the making of capacitors, were dispersed in nineteen pure organic liquids and water. The dispersions were characterized according to sediment volume results. Further experiments were performed to qualify the effects of moisture, particle concentration, and particle size distribution. Scanning electron micrographs of centrifuge casts of each powder in their best and worst dispersing medium were used to characterize further the dispersions. Results showed that alcohols and aldehydes were the best pure liquid dispersing mediums and hydrocarbons, ketones, and ethers were poor. The best results were obtained for a narrow-sized zirconia powder dispersed in methanol.
