| Abstract: | The morphological characteristics of α-Al2O3 crystallites obtained directly from hydro/solv othermal solvents are reported and the formation mechanisms of corundum morphology
are discussed from crystal growth and crystal chemistry principles. The crystal growth process is considered as a process
of incorporation of growth units on the growth interfaces, and the crystal morphology is determined by the linkage of the
coordinated polyhedra. |
