Abstract:
Sintering and many problems in adsorption and catalysis require an understanding of the surface structures of crystals, which have been subjected to various types of heat treatment. For example, heat treatment of m-plane sapphire surfaces can cause a transformation from a flat vicinal surface into those of a faceted hill-and-valley structure. Many technologically interesting materials form with the garnet structure, including YIG, YAG, GGG and many silicates. However, there has been relatively little discussion of the structure and behavior of such surfaces. This paper illustrates the use of visible-light microscopy (VLM), atomic-force microscopy (AFM) and scanning electron microscopy (SEM) for studying the ﹛111﹜ surface of gadolinium gallium garnet (GGG or Gd 3 Ga 5 O 12 ). 2x2x1 mm samples of monocrystalline GGG with ﹛111﹜ surface orientation were heat treated in air at 1575°C for 24 hours in order to study the processes a surface undertakes while reaching its equilibrium state.
