| Abstract：With MnCl2 and NaOH as raw material, hyperfine MnO2 is prepared by using supercritical fluid drying (SCFD) method. The XRD、particle size distribution technique and SEM are used to characterize the hyperfine MnO2 particles. The results show that the nanometer size and fine of MnO2 particle decreases largely in comparison with that prepared by conventional method. |
