This idea applies equally in a single, two, and 3-dimensional spaces. The entire crystal lattice is often produced by regularly reproducing the pattern of your unit mobile in all directions.
⒉棉、云雾或渣状包裹体、杂质在透明水晶内部有雾蒙蒙的现象或是感觉里面像有棉絮状、渣状物质一样的包裹体，这些包裹体的存在，影响水晶的整体美观。还有的水晶内局部含有黑斑或其他颜色的斑状物质，与水晶整体不协调，被视为水晶的杂质，有这种杂质的水晶是次品。
水晶文化历史悠久，古人曾赋予它一串极富美感的雅称：水玉、水精、水碧、石英等。
We've written about around three hundred stones during the mineral kingdom! Examine Each individual stone's unique origin, historical past, and energies down below.
. These 4 constructions comprise a lot of the binary crystals with equal numbers of cations and anions.
Not all crystals type in water, but nearly all crystals variety a similar way, atoms appear jointly and become a uniformed cluster. The process may take as minimal as a few days to it's possible a thousand a long time. Purely natural crystals that come from the Earth form a similar way.
Crystals search one of a kind from a number of other rocks and minerals, but �?barring a couple of Specific conditions �?nearly all minerals cover a crystalline framework beneath the floor.
Like a hot Remedy cools or perhaps a saturated Option evaporates, particles draw shut adequate for chemical bonds to kind. Crystals also can sort from deposition straight from the fuel stage. Liquid crystals possess particles oriented within an structured way, like sound crystals, nevertheless can easily move.
A lot of crystals behave like butter in that they're hard at small temperatures but soft at increased temperatures. They may be called solids in the slightest degree temperatures under their melting level. A feasible definition of the strong is definitely an item that retains its condition if remaining undisturbed. The pertinent difficulty is just how long the item retains its shape. A hugely viscous fluid retains its condition for an hour or so although not a year. A good should keep its condition longer than that.
颜色：无色，浅至深的紫色，浅黄、中至深黄色，浅至深褐、棕色，绿至黄绿色，浅至中粉红。
15The trick to a very good thermoelectric content is actually a crystal structure through which electrons can move 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 sodium chloride crystal lattice is characterised with the close packing in the favourable click here sodium ions and negative chloride ions. Every single sodium ion is surrounded by six chloride ions, and each chloride ion is surrounded by six sodium ions, creating a extremely steady and symmetrical construction.
14For instance, we have Quartz crystal clocks and watches precise to inside just one minute a 12 months.例如，我们使用的每年误差不超过1分钟的石英水晶钟表和手表。
水晶的价值根据品质、块体的大小、美感和产量多少的不同相差较大。遇到好的天然水晶要敢于下手，但好的水晶一般大家都想得到，值与不值，就要看经验了。由于天然水晶的开采和制作原因，没有瑕疵的水晶很难得到，纯净的饰品要达到与合成水晶媲美的品质，实在是很难得。另外，由于水晶的特性，在佩戴过程中，也会改变其等级，比如因为某种原因，有可能会逐渐产生较大裂纹。
