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. %K hydrothermal %K crystallization %K α_Al-2O-3 %K crystallites %K morphology %K growth %K mechanisms. %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=01BA20E8BA813E1908F3698710BBFEFEE816345F465FEBA5&cid=96E6E851B5104576C2DD9FC1FBCB69EF&jid=DD6615BC9D2CFCE0B6F945E8D5314523&aid=136465757D61F860273906305032DF11&yid=8CAA3A429E3EA654&vid=BE33CC7147FEFCA4&iid=0B39A22176CE99FB&sid=D5C9DC4EF2F78008&eid=D5C9DC4EF2F78008&journal_id=1001-6538&journal_name=科学通报(英文版)&referenced_num=0&reference_num=0
