氧化钴

In chapter three, various theories and experience on the dispersion of nano-powders proposed by former researchers were generalized and reviewed. Technical standards and experimental process for determining technological parameters were suggested for the dispersion of nano-scaled metal oxides in aqueous medium according to their surface wettability, surface charge, the dependence of surface charge on pH and the compatibility of surfactants with pH and pH adjusting agents. Based on these suggested standards and experimental method, highly stable and dispersive aqueous suspensoid of nm-ZnO, nm-TiO〓, nm-Co〓O〓 and nm-MnO powders were prepared successfully and surface modification on these nano-powders was also achieved.
