轴性、光性：一轴晶正光性。正交偏光下所看到的一轴晶干涉图是独特的，其黑十字臂未达中心，形成中空的图案，俗称牛眼干涉图。中心部分通常为淡绿色或淡粉色。

A crystal construction focuses on how the atoms are organized inside the crystal. However, crystallographers have an interest in the overall condition and size in the crystal and its external characteristics. To accomplish this, they need to understand about the crystal system.
Encyclopaedia Britannica's editors oversee subject areas where they may have comprehensive know-how, regardless of whether from years of encounter attained by working on that information or by using analyze for an advanced degree. They create new content and validate and edit material received from contributors.
断口：贝壳状。断口也叫破口。它是指矿物被打击后产生不规则的破裂，破裂裂面凹凸不平称为断口。根据断口的形状可分为贝壳状和锯齿状。
你们都知道，拿起一个水晶棱镜，让一束阳光通过它，就会得到一个光谱，看起来就像一条连续的彩虹色带。
石英：《广雅》称水晶叫石英，色白如莹者又叫白。为附的异形字。司马相如《子虚赋》就�?�?雌黄�?�?之句。苏林解释：�?�?，白石英�?”。
There is a equivalent directive about crystal glass which differentiates between entire guide crystal, direct crystal and crystal.
Metallic Crystals: Metals frequently kind metallic crystals, the place several of the valence electrons are free to move all through the lattice. Iron, click here one example is, can sort unique metallic crystals.
Solids that have limited-assortment get but absence extensive-variety order are known as amorphous. Nearly any materials could be built amorphous by immediate solidification within the melt (molten state). This problem is unstable, along with the sound will crystallize in time. In case the timescale for crystallization is a long time, then the amorphous condition seems steady.
15The trick to a good thermoelectric materials is usually a crystal framework by which electrons can stream freely.制造一种好的热电材料的关键是，需要一种电子可以自由流动的晶体结构。
The arrangement of the atom’s electrons decides its chemical Attributes. The Houses of solids tend to be predictable from your properties of their constituent atoms and molecules, and different shell structures of atoms are hence answerable for the range of solids.
crystal, any solid product wherein the part atoms are arranged in a definite sample and whose floor regularity reflects its interior symmetry.
The C60 molecules, also called buckyballs, are pretty solid and almost incompressible. Crystals are shaped these types of which the balls are arranged within an fcc lattice using a a person-nanometre spacing in between the centres of adjacent balls. The identical C70 molecule has The form of the rugby ball; C70 molecules also type an fcc crystal when stacked collectively. The sound fullerenes sort molecular crystals, with weak binding—furnished by van der Waals interactions—among the molecules.
