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 attempted once 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 advancements contain exotic buildings with programmable lattice symmetries and nicely-outlined crystal routines, responsive products that leverage the intrinsic Houses of nucleic acids to manipulate constructions on desire, nanoparticle superlattices developed epitaxially from surfaces and colloidal crystals that supply insights into gentle–make a difference interactions. Wanting ahead, we challenge the Neighborhood to leverage the amazing structural Command afforded by crystal engineering with DNA to synthesize classes of practical resources that press outside of what has long been probable with By natural means taking place crystalline materials or those produced by extra common techniques.
Encyclopaedia Britannica's editors oversee matter spots through which they have got extensive understanding, no matter if from a long time of encounter acquired by focusing on that articles or through review for a sophisticated degree. They write new material and verify and edit articles acquired from contributors.
There are actually many alternative crystals dependant upon geometric structures, crystal expansion, and materials. There could be preparations of hexagonal carbon atoms or amethyst that makes hexagonal pyramid buildings.
⑧、雕刻：立体感强，工艺高，做工精细，成本高。分手工雕刻图形、机器雕刻文字。
⑩、雷射内雕：以计算机辅助激光设备在水晶对象中进行三维图案的成型，艺术效果好，可以任意表达各类图案，图形，达到逼真效果
市场上有很多人把熔炼水晶也叫做合成水晶，那是不准确的，一般都是以水晶废料为原料在高温高压下熔炼出来的，而不是结晶成的，不具备水晶的晶体特性，所以不能把熔炼水晶与合成水晶混为一谈；但是熔炼水晶耐高温，用优质二氧化硅熔炼成的熔炼水晶可以做成实用产品比如水晶杯、烤盘、茶具等，实际上一代伟人毛泽东主席的水晶棺就是选用东海优质水晶熔炼而成的。
A lot of crystals behave like butter in that they are tricky at minimal temperatures but smooth at larger temperatures. They may be called solids at all temperatures below their melting level. A possible definition of a solid is really an object that retains its form if remaining undisturbed. The pertinent concern is how much time the thing keeps its condition. A highly viscous fluid retains its shape for an hour but not a yr. A stable should retain its shape extended than that.
晶体 Silicon crystals grown in a very laboratory convert mild into electrical Power. 在实验室中长成的硅晶体可将光线转变为电能。
天然性是水晶观赏石的基本特性。通常整体造型水晶矿物不饰雕琢就具备很高的观赏价值，但是包裹体水晶观赏石经常需要适当打磨抛光，这样更方便观赏水晶内部的包裹体。
Molecular Crystals: Overall molecules are bonded to one another in an arranged fashion. An excellent example can be a sugar crystal, which includes sucrose molecules.
The construction of the sodium atoms by yourself, or perhaps the chlorine atoms on your own, is fcc and defines the device mobile. The sodium chloride structure thus is designed up of two interpenetrating fcc lattices. The cesium chloride lattice (Figure 3A) is predicated on the bcc composition; every single other atom is cesium or chlorine. In this instance, the device cell is often a dice. The third essential framework for AB
