Strain of plates of aluminum, glass, and silicon at sorption of water vapor

It has been suggested and realized a kinetic approach to the investigation of sorbostriction isotherms on plates of aluminum, glass, and monocrystalline silicon at the sorption of water from its vapor. It is established increasing the plate area and decreasing the plate thickness with passing the contraction through a minimum in the process of sorption. The strain observed is explained by the interference of two effects: the influence of variation of the surface tension of the outer surface of samples and the role of micropores (with possible chemisorption in them).
