This research is aimed at solving crucial problem to diagnose and prognosticate moistening of fine-grained (finely-dispersed) materials. The article considers the dependence of surface moistening from the nature of the primary acid-base center. It demonstrates the advantages of acid-base property study of the surface applying the hydrolytic adsorption method. The research of hydrolytic adsorption on the ferric oxide with a haematite structure was carried out. Ferric oxide is presented in various states (massive and in the form of oxide film on the iron core of nanometer size). The identification of the composition and structure of the ferric-oxide compound was carried out applying the method of transmission electron microscopy (TEM) and X-ray diffraction analysis (XRDA). The authors found out the identity of the behavior characteristics of hydrolytic adsorption on the haematite in various states. The paper also describes the inhibition mechanism of haematite moistening, which explains its hydrophobic behavior. The material of this article can be useful for its implementation in industrial, research and school laboratories.
