| 中文摘要 | Magnesia whiskers with a diameter of 1-50 mu m and a length of 50-2000 mu m were synthesized via calcinations at different stages using MgCl2 center dot 6H(2)O as raw materials and KCl as flux. Through theoretical analysis of bischofite's pyrolysis and chemical analysis of intermediate products during different sintering stages, anhydrous magnesium chloride was presumed to be the precursor, which was confirmed by the preparation of MgO whisker from anhydrous magnesium chloride. Three factors that influence the whiskers morphology were also discussed including MgCl2, HCl and H2O. During the whisker's growth, heterogeneous nucleation of MgO occurs on the container-wall at initial stage, and then MgO whiskers are grown through VLS mechanism, finally dominated by VS mechanism.
