| Abstract: | MnO_2 ultrafine particles were prepared by colloidal chemical method. The most favorable experiment conditions for the preparation of MnO_2 UFP were researched. XRD, DTA, TG, TEM, IR examinations were used to investigate the characteristic of the sample. The spherical amorphous ultrafine MnO_2 product has an averaged diameter of 8.0 nm with good dispersity and transparent in many organic solvents. |
