摘要
In order to investigate the microstructure of magnesium oxide hydration product within seawater, two reaction conditions (liquid-solid and gas-liquid-solid) and two solutions (seawater and deionized water) were adopted for magnesium oxide hydration. The characterization of the hydration product using X-Ray diffraction and scanning electron microscope was performed. Experimental results indicate that cations and anions in seawater promote the hydration. Most of the hydration products within seawater system display flower-like morphology, but the agglomeration phenomenon is not obvious within deionized water system, especially for the supernatant layer products within deionized water system under gas-liquid-solid reaction condition. There was no stratification phenomenon occurred when MgO hydrated with seawater under three-phase reaction condition.
