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。
A elementary idea in crystal structures is the unit mobile. It is the smallest unit of volume which allows identical cells to be organized jointly to occupy all out there House. The geometrical basis of all crystals would be the lattice. A lattice is often considered as a regular and infinite arrangement of factors or atoms, wherever Every point or atom has A similar encompassing surroundings.
看做工：水晶制品加工过程分为两种，即磨工和雕工。如水晶项链、手链、耳环等属于研磨品；观音像、内画鼻烟壶等属于雕刻品。
Encyclopaedia Britannica's editors oversee issue parts through which they may have intensive information, irrespective of whether from yrs of working experience acquired by working on that written content or by means of examine for a complicated diploma. They produce new material and verify and edit information been given from contributors.
You will discover many different crystals depending on geometric structures, crystal growth, and material. There may be arrangements of hexagonal carbon atoms or amethyst which makes hexagonal pyramid constructions.
你们都知道，拿起一个水晶棱镜，让一束阳光通过它，就会得到一个光谱，看起来就像一条连续的彩虹色带。
根据包裹体和主晶宝石之间形成的先后关系可将水晶的包裹体划分以下三种类�?
Ionic Crystals: Electrostatic forces kind ionic bonds. A typical instance is a halite or salt crystal.
Q.four. Exactly what is the distinction between atomic framework and crystal construction? Ans. The principal difference between atomic composition and crystal composition lies in their definitions: atomic structure refers to how atoms are arranged inside of a solitary molecule or perhaps a cluster of molecules, whereas crystal structure problems the specific arrangement of atoms within a sound material.
多色�?无色水晶没有多色性。有色水晶有弱到强的多色�?表现为体色的不同深浅。
被主体水晶所捕获的包裹体。原生包裹体通常为固相，形态较规则。水晶中典型的原成包裹体有金红石、电气石、黄铁矿等，也会见到岩石碎屑或集合体。
The sodium chloride crystal lattice is characterized with the close packing on the favourable sodium ions and destructive chloride ions. Each sodium ion more info is surrounded by 6 chloride ions, and every chloride ion is surrounded by six sodium ions, developing a really secure and symmetrical structure.

The C60 molecules, also referred to as buckyballs, are pretty powerful and Just about incompressible. Crystals are formed these types of the balls are organized within an fcc lattice by using a one-nanometre spacing amongst the centres of adjacent balls. The comparable C70 molecule has the shape of the rugby ball; C70 molecules also sort an fcc crystal when stacked alongside one another. The solid fullerenes sort molecular crystals, with weak binding—provided by van der Waals interactions—among the molecules.
