在铁氧化物的酸碱和吸附性能的研究框架内，在几个实验室参加一个共同的项目进行了彻底的表征两种类型的针铁矿粉。ICPAES化学分析;高分辨率SEM、TEM和AFM观察;具有线宽分析的XRD;以及氩和氮吸附等温线用于该目的。针铁矿颗粒的主要晶面为{001}、{101}和{121}，其丰度与低压氩吸附等温线的分布有关。这些结果对进一步研究水溶液中的表面活性与固体表面取向的关系具有重要意义。
In the framework on a study of the acido-basic and sorption properties of iron oxides, a thorough characterization of two types of goethite powders was performed in several laboratories joined in a common project. Chemical analysis by ICPAES; high-resolution SEM, TEM, and AFM observations; XRD with line width analysis; and argon and nitrogen sorption isotherms were used for that purpose. The main crystallographic faces of goethite particles could be identified as {001}, {101}, and {121}, and their abundance correlated with the distribution of low-pressure argon adsorption local isotherms. These results will be very useful for further studies on the relationship between surface reactivity in aqueous solution and orientation of solid surfaces.
