Not all crystals are Similarly crystalline. There are frequently impurities, and also the ionic & covalent among molecules can generate vastly different constructions out of precisely the same substance. An excellent example of this are diamonds and graphene.

水晶文化历史悠久，古人曾赋予它一串极富美感的雅称：水玉、水精、水碧、石英等。
The purchased inner composition of huge crystals, much like the fluorite and quartz revealed right here, is mirrored of their geometric styles.
《全唐诗》卷七八五载《白雪歌》：“鸟啄冰潭玉镜开，风敲檐溜水晶折。”
, has precisely the same construction, but there are two options for selecting the holes the atoms will occupy. The 3rd layer could be positioned over the atoms of the initial layer, making an alternate layer sequence A
Springer Mother nature continues to be neutral with regard to jurisdictional claims in printed maps and institutional affiliations.
Crystals are absolutely nothing greater than an purchased arrangement of molecules or atoms. Crystals can be found in a number of sizes and shapes, and every one has different characteristics. Whatever they are created of decides how it's going to variety.
第三种是“皮景”，因某些其他的矿物与水晶体共生，或由于其他的物质侵蚀而依附于水晶表面，或者是水晶受自然环境的影响，在水晶表面出现蚀象，形成了一些景象或图案，这种景观存在于水晶表面。
crystal The newly crystallized quartz grains are characterised by elongate crystals oriented oblique into the shear band margins, defining an average grain-shape foliation. 来自 Cambridge English Corpus We are saying the chain topology while in the substantial w area acts as being the proverbial ' scratch-on-theglass ' needed from the natural and organic chemistry laboratory to help make crystals. 来自 Cambridge English Corpus The age scatter amid the person crystals might reflect incorporation of xenocrysts from earlier magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene sorts neutral to pale brown, subhedral to anhedral crystals, occasionally that contains inclusions of plagioclase microlaths and opaque phases.
15The trick to a great thermoelectric substance is a crystal structure wherein electrons can flow 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。
You can find other minerals and molecules that could kind these crystal lattices. Snowflakes can be a classic example of a around symmetric and geometrically patterned framework from ice crystals, and gemstones of all varieties are generally crystals.
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。
The C60 molecules, also called buckyballs, are very powerful and Nearly incompressible. Crystals are shaped such that the balls are organized in an fcc lattice that has a a single-nanometre spacing in between the centres of adjacent balls. The related C70 molecule has The form of the rugby ball; C70 molecules also variety an fcc crystal when stacked alongside one another. The stable fullerenes variety molecular crystals, with weak binding—supplied by van der Waals interactions—between check here the molecules.
