Abstract

Dissolution of single-crystal spheres of fluorite in the acid pH range always results in final dissolution forms that are mainly composed of (100) terraces. Any (100) face can only occur as the result of a face-specific adsorption effect. Such an effect was explained in earlier studies through the existence of (100) faces completely terminated by OH (super -) ions, and a water layer linked by hydrogen bonds to the OH layer. However, this assumption can hardly explain the formation of (100) terraces in the presence of 1 M to 5 M acids. A slight modification of Glikin's theory is proposed to explain the formation of (100) even in strongly acidic environments.
