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。
If you'd like to see how crystals are shaped, you are able to do a little venture as part of your extremely have kitchen and find out the formation with the crystals manifest with the own eyes . This may be performed by putting a little quantity of table salt into some normal faucet drinking water, hold out 24 several hours, and you may see pleasant cubed formations. This occurs as the water is evaporating, which causes the atoms which make up the salt (the mineral) and the h2o to come back closer together.
Additionally, there are several materials that resemble crystals but are actually polycrystals. Polycrystals variety when microscopic crystals fuse with each other to sort a strong. These components never consist of purchased lattices.
Not all crystals form in h2o, but nearly all crystals form the check here same way, atoms arrive with each other and become a uniformed cluster. The method will take as minor as a couple of days to it's possible a thousand several years. Natural crystals that originate from the Earth form the exact same way.

Crystals could be grown below moderate problems from all ninety two naturally taking place features apart from helium, and helium may be crystallized at low temperatures by making use of 25 atmospheres of tension.
13Nearly all computer systems include a quartz-crystal clock to manage their operation.几乎所有的计算机都有一个石英晶体时钟来调节它们的运行。
晶体 Silicon crystals developed in the laboratory change mild into electrical Power. 在实验室中长成的硅晶体可将光线转变为电能。
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。
