诗中“胜美玉”，“过冰清”，写出水晶的质地美，而“亦欲应时明”则描绘出水晶充满灵性的动态美，耐人寻味。罗维是有独特眼光，懂得水晶真谛，第一个称赞水晶超过美玉的伟大诗人。他的认识已被千年之后的科学理论所证实；以水晶为直接吟咏对象的诗篇还有：
12He tried out all over again in many other towns and succeeded with Crystal Caramels.他又在其他几个城市再次尝试，并成功制出了水晶焦糖。
These improvements consist of unique constructions with programmable lattice symmetries and very well-outlined crystal practices, responsive supplies that leverage the intrinsic Qualities of nucleic acids to control buildings on desire, nanoparticle superlattices developed epitaxially from surfaces and colloidal crystals which offer insights into mild–matter interactions. Hunting ahead, we obstacle the Local community to leverage the amazing structural Manage afforded by crystal engineering with DNA to synthesize lessons of useful supplies that thrust beyond what continues to be possible with By natural means occurring crystalline materials or People produced by much more regular approaches.
If you wish to see how crystals are shaped, it is possible to perform a little task in the really own kitchen area and find out the development in the crystals manifest with the possess eyes . This may be performed by Placing a small quantity of table salt into some frequent faucet h2o, wait 24 hrs, and you may see nice cubed formations. This takes place as the drinking water is evaporating, which will cause the atoms that make up the salt (the mineral) as well as the drinking water to come back nearer together.
水胆水晶，包括气态，液态，固态，有时候可以同时多态并存，无色居多，个别情况下可见红色，绿色，黄色，蓝色，黑色等。
Monoclinic �?Characterised by three unequal axes, two of which intersect at an oblique angle, though the 3rd is perpendicular towards the plane of the check here other two.
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�?”。
Crystals can be grown beneath moderate ailments from all ninety two Normally taking place things other than helium, and helium may be crystallized at small temperatures by making use of 25 atmospheres of force.
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。
广义的包裹体是指宝石内部含有的与主晶宝石化学成分、物理性质等不同的物质。
用手去触摸水晶，天然水晶通常温度要比人造水晶的要凉的多；用眼观察，天然水晶通常有棉絮状的包裹体，这个是人造水晶所没有的。
Molecular Crystals: Complete molecules are bonded to each other in an arranged manner. A great instance can be a sugar crystal, which incorporates sucrose molecules.
Crystals are categorised on the whole types, which include insulators, metals, semiconductors, and molecular solids. An individual crystal of the insulator will likely be clear and resembles a piece of glass. Metals are shiny Except if they've got rusted. Semiconductors are occasionally shiny and from time to time transparent but are under no circumstances rusty. Quite a few crystals can be categorised as an individual form of reliable, while others have intermediate conduct. Cadmium sulfide (CdS) could be geared up in pure variety and is a superb insulator; when impurities are added to cadmium sulfide, it gets to be an interesting semiconductor.
