These crystals were fashioned over one million years in the past inside the Earth's crust. They manifest if the liquid in the Earth consolidates along with the temperature chills. Other crystals sort in the event the liquid can make its way in the clefts and dispense minerals in the clefts.
①压电效�?在机械力(压力或拉�?作用下，水晶单晶体的两端会产生电荷，其电量相等但符号相反。在工业上，无色、无缺陷、不具双晶的水晶常被用来作压电石英片。
Chemical Bonds The types of chemical bonds formed concerning atoms or teams of atoms in crystals depend on their size and electronegativity. You will find 4 types of crystals as grouped by their bonding:
Tetragonal: These crystals form prisms and double pyramids. The composition is like a cubic crystal, other than one particular axis is extended than the opposite.
看抛光：抛光的好坏直接影响到水晶制品的身价。抛光分为软抛光与硬抛光。
Not all crystals variety in h2o, but nearly all crystals form the exact same way, atoms occur with each other and turn into a uniformed cluster. The procedure will take as very little as a few days to maybe a thousand yrs. Natural crystals that come from the Earth kind the same way.
⑦、镀彩：运用类似电镀的手法在水晶表面以不同的色彩，层面较薄，经摩擦可划伤�?；出现划痕，由于镀彩经常位于底部，因此在镀彩底部经常采用其它对象附着，如生肖文镇。

Q.four. What's the distinction between atomic composition and crystal structure? Ans. The primary difference between atomic framework and crystal composition lies of their definitions: atomic construction refers to how atoms are organized in just a one molecule or even a cluster of molecules, Whilst crystal framework fears the precise arrangement of atoms inside of a strong substance.
The definition of more info a good appears noticeable; a sound is generally thought of as getting tough and firm. Upon inspection, having said that, the definition gets to be much less straightforward. A cube of butter, such as, is hard soon after remaining stored in a refrigerator and it is Evidently a sound. Right after remaining to the kitchen area counter for every day, the same cube gets to be rather tender, and it really is unclear If your butter ought to however be considered a stable.
地质学家目前为止对晶洞形成还没有广泛认同的理论，但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴，甚至动物挖的地洞。经过漫长时间，空腔的外壁变硬，溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间，缓慢渗入的矿物使得晶体在空腔内部结晶。
Crystal Lattices There are actually seven systems of crystal constructions, that are also referred to as lattices or Area lattices:
⑦双色水晶：一种紫色和黄色共存一体的水晶，紫色、黄色之间界限较明显，分别占据晶块的一部分。
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。
