摘要
Aiming at the dispersion of nano-zirconia regarded as the guide of inorganic membranes preparation, the dispersion of nano-zirconia powders in water was studied by adding different dispersants at different concentrations. In addition, the relationship between pH value and the dispersion was investigated. The results of experiments show that: (1) the dispersion of the suspension is drastically subject to the kinds of dispersants, the concentration of dispersants and the pH value of suspension; (2) different dispersants have different optimizing concentrations in their applicable range, which have the best disperse results. These suspensions were studied by means of determined particle size and zeta potential measurements. The results of dispersants were obtained through varying the pH value. Finally, the optimizing range of pH values was studied.
