中文百科
晶体结构![]() ![]() ![]() ![]() ![]() 晶体结构是指晶体的周期性结构。固体材料可以分为晶体、准晶体和非晶体三大类,其中,晶体内部原子的排列具有周期性,外部具有规则外形,比如钻石(图)。 Hauy最早提出晶体的规则外型是因为晶体内部原子分子呈规则排列,比如钻石所具有的完美外形和优良光学性质就可以归结为其内部原子的规则排列。20世纪初期,劳厄发明X射线衍射法,从此人们可以使用X射线来研究晶体内部的原子排列,其研究结果进而证实了Hauy的判断。 晶体内部原子排列的具体形式一般称之为晶格,不同的晶体内部原子排列称为具有不同的晶格结构。各种晶格结构又可以归纳为七大晶系,各种晶系分别与十四种空间格(称作布拉维晶格)相对应,在宏观上又可以归结为三十二种空间点群,在微观上可进一步细分为230个空间群。
英语百科
Crystal structure 晶体结构![]() ![]() ![]() ![]() In mineralogy and crystallography, a crystal structure is a unique arrangement of atoms, ions or molecules in a crystalline liquid or solid. It describes a highly ordered structure, occurring due to the intrinsic nature of its constituents to form symmetric patterns. |
