摘要: The surface chemistry differences between two alumina powders is shown to have a significant effect on the properties of concentrated aqueous dispersions powders. initial dispersion pH and magnitude sign mobility particles (determined by acoustophoresis) are different for because in impurity contents. As result, require amounts dispersant achieve stability near their isoelectric points. these aluminas illustrate importance examining ceramic at concentrations used processing material.
