| 摘 要： | 研究了电场对铝酸钠溶液自发分解的强化作用,借助扫描电镜和X-射线衍射仪分析了分解产物的形貌和物相组成。结果表明:在电场作用下,铝酸钠溶液的自发分解率显著提高;电场有效促进了初生晶核的形成,缩短了成核诱导期,而且不会改变铝酸钠溶液分解产物的物相,分解产物仍为三水铝石。

| Abstract: | The action of electric field on spontaneous decomposition of sodium aluminate solution was studied.By XRD and SEM,the surface topography and phase composition of decomposition product of sodium aluminate solution was analyzed.The electric field can promote effectively primary nuclei to form,but cannot change the phase composition of decomposition product.The product was still gibbsite. |

| Keywords: | electric field enhancement sodium aluminate solution decomposition gibbsite |
