Morphological characteristics of α-Al_2O_3 crystallites obtained directly from hydro/solvothermal solvents |
| |
摘 要: | The morphological characteristics of α_Al-2O-3 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.
