Abstract:In this paper,the magnesium was electrolyzed at the current of 0.2A for Sh in ethanol and acetyl-acetone solution of 0.04mol/L(Bu4)NBr,and then the precursor Mg(OEth-x(acac)x of MgO was obtained by anodic dissolution.The xerogel of MgO was prepared by a direct sol-gel process of the electrolyte solution under pH:8.0.IR.spectrum,TG-DTA,XRD,and TEM were used to investigate the structure of the precursor and nano-sized MgO.The results show that nano-sized MgO with a narrow size distribution of around 12nm can be obtained at a low temperature of soot.This process may be recomeded as a promising method to synthesize the other nano-powder.
