晶体

石英 晶体
合成铋单晶
胰岛素晶体
镓,一种很容易结成大块单晶的金属

晶体是原子、离子或分子按照一定的周期性,在结晶过程中,在空间排列形成具有一定规则的几何外形的固体。

晶体的分布非常广泛,自然界的固体物质中,绝大多数是晶体。气体、液体和非晶物质在一定的合适条件下也可以转变成晶体。

晶体内部原子或分子排列的三维空间周期性结构,是晶体最基本的、最本质的特征,并使晶体具有下面的通性:

  • 均匀性,即晶体内部各处宏观性质相同;
  • 各向异性,即晶体中不同的方向上性质不同;
  • 能自发形成多面体外形;
  • 有确定的、明显的熔点;
  • 有特定的对称性;
  • 能对X射线和电子束产生衍射效应等。

Crystal 晶体

A crystal of amethyst quartz
Halite (table salt, NaCl): Microscopic and macroscopicMicroscopic structure of a halite crystal. (Purple is sodium ion, green is chlorine ion.) There is cubic symmetry in the atoms' arrangement.Macroscopic (~16cm) halite crystal. The right-angles between crystal faces are due to the cubic symmetry of the atoms' arrangement.
Halite crystal (Macroscopic )
As a halite crystal is growing, new atoms can very easily attach to the parts of the surface with rough atomic-scale structure and many dangling bonds. Therefore, these parts of the crystal grow out very quickly (yellow arrows). Eventually, the whole surface consists of smooth, stable faces, where new atoms cannot as easily attach themselves.

A crystal or crystalline solid is a solid material whose constituents, such as atoms, molecules or ions, are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations.
