其它描述：《庶物异名疏》中说： �?水精出大秦国，一名黎�?�?。结晶完整的水晶晶体，就如参差交错的马齿，所以人们又叫它马牙石。先民们最早用它研磨成眼镜片，因而送它一个眼镜石的绰号。水晶有通称，也有俗称。广州一带称水晶叫晶玉，又名鱼脑冻；江苏东海县山民发现水晶会 �?窜火�?�?，于是给它起个放光石的俗名。世间一物多名，不足为奇，而像水晶拥有这么多的别称，实不多见。瞧，从水玉、水碧、白玉、玉瑛、水精石英、黎难、晶玉到菩萨石、马牙石、眼镜石、放光石、千年冰、高山冻、鱼脑冻等等，简直构成一部奇石鉴赏史。
An additional enjoyable, and tasty, experiment should be to variety significant crystals applying sugar. By heating sugar with drinking water after which permitting this Resolution evaporate on sticks, it is possible to form rock candy from sugar crystals!
A crystal construction focuses on how the atoms are arranged In the crystal. On the other hand, crystallographers have an interest in the overall form and dimensions with the crystal and its exterior properties. To perform this, they should understand about the crystal program.
Massive crystals of diamond are important gemstones. The crystal has other exciting Homes; it's got the highest audio velocity of any stable and is the greatest conductor of warmth. Apart from diamond, another widespread kind of carbon is graphite, that is a layered substance. Each and every carbon atom has 3 coplanar close to neighbours, forming an arrangement called the honeycomb lattice. A few-dimensional graphite crystals are acquired by stacking very similar layers.
这种水晶观赏石特指水晶晶簇，它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。
无色水晶与无色长石因折射率和密度十分接近故较难区分。主要方法是放大检查。长石有两组极完全解理，显微镜下可见两组解理相交而成的“娱蛤状”包裹体或细直的纹理，而水晶则无解理发育，仅有时可见断续不规则的裂理。
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：
Crystals could be developed below average ailments from all ninety two In a natural way happening factors apart from helium, and helium may be crystallized at small temperatures through the use of 25 atmospheres of tension.
Among the many binary crystals, the best constructions to visualise are These with equivalent numbers of The 2 varieties of atoms. The composition of sodium chloride is based on a dice. To construct the lattice, the sodium and chlorine atoms click here are put on alternate corners of a dice, plus the framework is repeated (Determine 3B).
看文化：水晶里面的包裹体象形，能与文化、宗教及历史有所牵连的话，价格往往会比水晶本身的价值高出几倍甚至几百倍。
15The trick to a very good thermoelectric materials is really a crystal construction through which electrons can movement 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 establishes its chemical Homes. The Qualities of solids usually are predictable in the Qualities of their constituent atoms and molecules, and the different shell structures of atoms are hence liable for the diversity of solids.
水玉：中国最古老的称法叫水玉，意谓似水之玉，又说是 �?千年之冰所�?�?。唐代诗人温庭筠《题李处士幽居》写道：�?水玉簪头白角巾，瑶琴寂历拂轻�?”。水玉一词最早频繁出于《山海经》：�?又东三百里，日堂庭之�?…�?多水�?”；�?丹山出焉，东南流注于洛水，其中多水玉 ”；�?逐水出焉，北流注于渭，其中多水玉 ”。司马相如《上林赋》曰�?�?水玉磊河 �?。水晶得名水玉，古人是看�?�?其莹如水，其坚如�?�?的质地。
This crystal framework is to blame for the exclusive physical and chemical properties of sodium chloride, together with its significant melting point, electrical conductivity, and skill to sort ionic bonds effortlessly.
