School of Chemistry and Chemical Engineering, Central South University, Changsha 410083, China）Abstract: The change rules of precipitation ratio, microstructure and particle size and the effect of oleic acid on the seed precipitation of sodium aluminate solution were investigated. According to these experimental results, the total energy and electronic structure of oleic acid locating on gibbsite (001) and face (100) with different modes were calculated, and the equilibrium and growth morphology of the systems were analyzed.

摘 要：研究添加油酸杂质时，铝酸钠溶液分解过程中分解率、氢氧化铝产品的形貌和粒度的分布变化规律；计算以各种不同方式位于氢氧化铝的(001)和(100)面时油酸分子的总能量和电子结构，并分析各体系的平衡形态及生长习性。

Calculation results indicate that the total energy increases when oleic acid is on the surfaces of (001) and (100) of gibbsite respectively. This can explain that the stability of systems decrease when there is some oleic acid on the surface of gibbsite. The calculation results of equilibrium morphology and growth habit show that the volume of growth crystal is larger when some oleic acids with "horizontal" mode exist on the surfaces (001) and (100) of gibbsite.

计算结果表明：油酸接近氢氧化铝(001)和(100)表面时，体系总能量升高，说明油酸的存在可降低体系的稳定性；油酸在氢氧化铝(001)和(100)表面上时，油酸分子呈"卧"式时，长大后晶粒体积大于无杂质存在的情况，而油酸分子呈"立"式时，长大后体积小于无杂质时晶粒的体积。
