Magnesi um oxalate hollow nanospheres were obtained though grinding directly grinding ma gnesium acetate and oxalic acid.

The intermediate and residue of each decomposition were identified from their TG curve. The kinetic triplet, the activation energy E, the pre-exponential factor A and the mechanism functionsf（a） were obtained from analysis of the TG-DTG curves of thermal decomposition of the first stage and the second stage by the Popesou method and the Flynn-Wall-Ozawa method.展开更多
