Abstract
The ideal dissolution forms of crystals are discussed. The ideal dissolution form of corundum is compared with its real forms, obtained under different experimental conditions, and with its simple forms expected on the basis of structural observations. Anisotropy of the dissolution rates of sapphire and ruby spheres is shown. On the basis of kinetic data it is concluded that the rate of the chemical reaction between corundum and reagent controls the thermochemical dissolution of corundum. The possible chemical reactions determining dissolution are estimated.
