The dissolution forms of YIG single crystal spheres

Abstract Single crystal spheres of yttrium iron garnet have been dissolved in solvents of H 3 PO 4 and HBr at 140 and 126°C, respectively. The final dissolution form was a tetrahexahedron in H 3 PO 4 and an octahedron in HBr. In the latter case the faces were built up of terraces. The observed dissolution forms could be explained using the theory of Lacmann, Franke and Heimann.
