在先前报告的工作的延续中[H。D.贝尔和P. W.施密特，J.物理学。化学，62,1179(1958)]利用小角度x射线散射技术，对不同方法制备的氢氧化铝凝胶的物理结构进行了进一步的研究。计算了准直校正对一些早期数据的影响，并进行了进一步的实验。以前，新鲜凝胶的散射被发现与沉淀进行时的pH值无关，并被证明取决于凝胶沉淀的铝盐阴离子的浓度和电荷。本研究表明，降水过程中阴离子浓度对散射模式的影响远大于铝离子浓度。在没有离子存在的条件下制备的凝胶的散射也进行了研究。由凝胶制成的溶胶的散射数据表明，凝胶可以…
In a continuation of previously reported work [H. D. Bale and P. W. Schmidt, J. Phys. Chem. 62, 1179 (1958)] a further study of the physical structure of aluminum hydroxide gels prepared by different methods has been carried out, using small angle x‐ray scattering techniques. The effects of collimation corrections on some of the earlier data have been calculated, and further experiments have been conducted. Previously, the scattering from the fresh gels was found to be independent of the pH at which precipitation was carried out, and was shown to depend on the concentration and charge of the anion of the aluminum salt from which the gel was precipitated. The present study shows that the anion concentration during precipitation has a much greater effect on the scattering pattern than does the aluminum ion concentration. The scattering from gels prepared under conditions in which no ions were present has also been studied. Scattering data from sols which are made from the gels indicate that the gels can be ...
