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 crystal structure concentrates on how the atoms are organized In the crystal. Having said that, crystallographers have an interest in the overall shape and dimension in the crystal together with its exterior characteristics. To perform this, they should know about the crystal procedure.
Fig. seven: A template-directed solution can Handle The position of making blocks with a area while in the formation of complicated constructions.
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。
Monoclinic �?Characterised by a few unequal axes, two of which intersect at an oblique angle, although the third is perpendicular to the aircraft of another two.
时尚的收藏爱好者喜欢收藏天然水晶，却常常因为在市场上面对大量的合成水晶看走了眼。市面上的水晶：

⑤化学稳定�?非常好，在常温下仅溶解于氢氟酸，不溶解于其它各类酸、碱。在高温高压条件下可溶解于碳酸钠溶液中。
One crystals of metals are gentle and malleable, while polycrystalline metals are tougher and much better and are more beneficial industrially. Most polycrystalline materials is usually produced into huge one crystals just after prolonged warmth treatment method. Up to now blacksmiths would warmth a bit of metallic to make it malleable: heat helps make a couple of grains improve large by incorporating lesser ones. The smiths would bend the softened metal into condition after which you can pound it awhile; the pounding would allow it to be polycrystalline again, rising its energy.
The click here sodium chloride crystal lattice is characterized from the near packing of the beneficial sodium ions and damaging chloride ions. Each individual sodium ion is surrounded by six chloride ions, and every chloride ion is surrounded by six sodium ions, making a highly secure and symmetrical construction.
crystal, any strong substance during which the component atoms are organized in a definite pattern and whose floor regularity reflects its interior symmetry.
The C60 molecules, also known as buckyballs, are quite strong and Nearly incompressible. Crystals are fashioned these kinds of the balls are arranged in an fcc lattice which has a 1-nanometre spacing in between the centres of adjacent balls. The very similar C70 molecule has The form of a rugby ball; C70 molecules also sort an fcc crystal when stacked collectively. The good fullerenes kind molecular crystals, with weak binding—provided by van der Waals interactions—amongst the molecules.
