中文摘要The composition of basic magnesium carbonate varies, mainly due to the decomposition conditions of magnesium bicarbonate. In the present study, we researched the specific composition of samples prepared at different decomposition temperatures of magnesium bicarbonate. Combining XRD, TG-DSC and wet chemical analysis, we found that single component which the formula is MgCO3 center dot 3H(2)O can be got at room temperature (30 degrees C). Content of MgCO3 center dot 3H(2)O in the decomposition products decreases with the increase of decomposition temperature. The decomposition products obtained at 90 degrees C is 4MgCO(3)center dot Mg(OH)(2)center dot 4H(2)O based and contain a little MgO, Mg(OH)(2), trace amount MgCO3 center dot 3H(2)O and 4MgCO(3)center dot Mg(OH)(2)center dot 5H(2)O. Further study show that content of MgCO3 center dot 3H(2)O influences the density of final product of magnesium oxide. Density of magnesium oxide got by calcining MgCO3 center dot 3H(2)O is 0.944 g.ml(-1), and density of magnesium oxide got by calcining product that was prepared at 90 degrees C is 0.078 g.ml(-1).
