Abstract

The adsorption isotherm of water, the IR spectra of adsorbed water, and the surface water content were measured on the surface of CaF₂. As the result, it was found that the step appears in the adsorption isotherm, being due to the two-dimensional condensation of water, as in the cases of such metal oxides as ZnO, SnO₂, and Cr₂O₃. The step decreased when the sample was heated in vacuo at increasingly elevated temperatures, and became extinct after the treatment at 600°C. Chemisorbed water was present on the surface of CaF₂.
