This concept applies Similarly in a single, two, and a few-dimensional Areas. The whole crystal lattice can be manufactured by regularly reproducing the pattern with the unit cell in all Instructions.

A crystal structure concentrates on how the atoms are arranged inside the crystal. Having said that, crystallographers have an interest in the overall condition and size with the crystal and its exterior attributes. To perform this, they should understand about the crystal technique.

Encyclopaedia Britannica's editors oversee subject matter areas wherein they have extensive awareness, no matter if from a long time of knowledge obtained by focusing on that articles or by means of review for an advanced degree. They compose new material and verify and edit content gained from contributors.

当二氧化硅结晶完美时就是水晶；结晶不完美的就是石英：二氧化硅胶化脱水后就是玛瑙；二氧化硅含水的胶体凝固后就成为蛋白石；二氧化硅晶粒小于几微米时，就组成玉髓、燧石、次生石英岩。

水晶的评价标准和高端宝石有所不同。多数高端宝石把颜色放在评价的第一位，而对水晶来说，颜色和净度（水晶行业称作晶体）是近乎同等重要的因素：

There exists a identical directive about crystal glass which differentiates amongst full direct crystal, lead crystal and crystal.

水晶常以晶簇、晶洞形式产出，其中水晶洞一般存在于由火山喷发而形成的巨厚熔岩流层的火成岩与玄武岩中。火山喷发时所含的气体或热水溶蚀等作用导致岩层中出现大量的孔隙，当富含硅质矿物的流体进入较薄的熔岩孔隙中，且温、压条件合适时将结晶沉淀出水晶等矿物。

晶体 Silicon crystals grown inside a laboratory change gentle into electrical Power. 在实验室中长成的硅晶体可将光线转变为电能。

Single crystals of metals are soft and malleable, when polycrystalline metals are more difficult and much better and are more useful industrially. Most polycrystalline materials is often made into significant solitary crystals immediately after extended warmth therapy. In the past blacksmiths would heat a bit of steel to make it malleable: warmth would make a number of grains expand large by incorporating scaled-down kinds. The smiths would bend the softened metal into shape after which you can here pound it awhile; the pounding would ensure it is polycrystalline again, expanding its power.

Crystal Lattices You will find 7 devices of crystal buildings, which happen to be also called lattices or Room lattices:

⑦双色水晶：一种紫色和黄色共存一体的水晶，紫色、黄色之间界限较明显，分别占据晶块的一部分。
