School of Chemistry and Chemical Engineering, Central South University, Changsha 410083, China）Abstract: Based on the theoretic calculation of crystal faces (001),(100),(010),(011),(110),(101) and (112) of gibbsite by CASTEP program, the relationship between unfold character of crystal face and chemical bond strength of surface of gibbsite was investigated.

摘 要：用剑桥连续总能量软件包程序，对氢氧化铝的各个经常显露面族的(001)、(100)、(010)、(011)、(110)、(101)和(112)面进行理论计算，分析氢氧化铝晶体的晶面显露特征与表面化学键力的关系。

It is found that from bond population calculation results, the bonding strength of Al—O bond of faces (011) and (011) of gibbsite are stronger than that of face (001). If the proportion of unfold of (001) surface is decreased and the proportion of unfold of (011) and (011) surfaces is increased to same possible extend, the bonding strength of Al—O bond of gibbsite would be more strong.

键布居分析结果表明，整体上氢氧化铝的(001)面的Al—O键的结合力不强，(011)和(110)面的Al—O键的平均键布居数较高，结合力较强；若小幅度降低(001)面的显露比例，并使(110)和(011)面较多显露，就有可能提高氢氧化铝表面的Al—O键的结合力。
