| Abstract: | Lattice gas model is presented for rhombohedral lattice.Seven ordered structure types and four perfectly ordered structures are determined using concentration wave theory.The ordered structures of cation in corundum-type dimetal trioxides are predicted and reasonable explanations for typical experimental results are given. |
| Keywords: | rhombohedral crystal concentration wave ordered structure corundum |
