Abstract

Single crystal spheres of gadolinium gallium garnet have been dissolved in acids. The activation energies for dissolution of Czochralski-grown and flux-grown crystals of GGG in H3PO4 between 100-200°C were 0.75 and 0.88 eV respectively. The final dissolution form was a tetrakishexahedron in H3PO4 and an octahedron in HBr. In the latter case the faces were built up of terraces. The relationship between the growth and dissolution forms is discussed.
