结合作者的量热测定结果和前人的工作，研究了氧化铝工业中最常见的几种铝化合物如α－Ａｌ_２Ｏ_３，γ－Ａｌ_２Ｏ_３，三水铝石一水软铝石和一水硬铝石的基本热力学性质：标准生成焓、标准熵、标准生成Ｇｉｂｂｓ自由能和热容，得到了可靠、自洽的结果．

An investigation on the thermodynamic properties of α-Al_2O_3, γ-Al_2O_3,gibbsite, boehmite and diaspore: standard enthalpy of formation, standard entropy, standard free energy of formation, and heat capacity was made based on calorimetric determinations and the published literatures. The reliability and consistency of the recommended values of these thermodynamic properties were discussed in detail.Correspondent: CHEN Qiyuan, professor,(Department of Chemistry, Central-South University of Technology, Changsha 410083)
