Not all crystals are Similarly crystalline. There are often impurities, and the ionic & covalent involving molecules can create vastly different buildings outside of the same product. An excellent illustration of this are diamonds and graphene.
23Sometimes, on the other hand, the crystal form of the silicate inclusions is noticed to resemble additional closely The inner construction of diamond than that of other silicate minerals.然而，有时观察到硅酸盐包裹体的晶体形态比其他硅酸盐矿物更接近金刚石的内部结构。
10This is definitely the silicon chip—just a little chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
Most strong products found in nature exist in polycrystalline type in lieu of as just one crystal. They are literally composed of an incredible number of grains (small crystals) packed alongside one another to fill all space. Each individual individual grain has a different orientation than its neighbours. Despite the fact that lengthy-assortment get exists within one grain, on the boundary amongst grains, the buying variations path. A normal bit of iron or copper (Cu) is polycrystalline.
根据美国已经了解的情况，统计局的专家和其他人口统计学家在他们的视野中提供了一个不可抗拒的水晶球。
Not all crystals sort in h2o, but almost all crystals sort precisely click here the same way, atoms come alongside one another and turn into a uniformed cluster. The process normally takes as tiny as a few days to probably a thousand many years. Organic crystals that originate from the Earth kind the identical way.
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：
Crystals can be grown below moderate conditions from all ninety two naturally developing things apart from helium, and helium might be crystallized at low temperatures by using twenty five atmospheres of strain.
第三种是“皮景”，因某些其他的矿物与水晶体共生，或由于其他的物质侵蚀而依附于水晶表面，或者是水晶受自然环境的影响，在水晶表面出现蚀象，形成了一些景象或图案，这种景观存在于水晶表面。
say cheese a thing that someone that is taking a photograph of you lets you know to mention so that your mouth tends to make the shape of a smile
. The second layer is shaded while in the figure. It's got the exact same airplane-triangular structure; the atoms sit during the holes shaped by the initial layer. The primary layer has two equal sets of holes, even so the atoms of the next layer can occupy only one set. The 3rd layer, labeled C
Crystal Lattices You will discover seven systems of crystal constructions, that happen to be also referred to as lattices or space lattices:
压电性：水晶晶体受到压力时会产生电荷；反之，受到电压作用时，晶体会产生频率很高的振动。水晶具有可使压力与电荷相互转移的性能，称压电性。
水晶观赏石是天然水晶中最具代表的作品，具有其他宝石都不具备的观赏性。不论是玉石翡翠还是都要经过雕琢后次能体现他的价值，而水晶观赏石只需要将表面进行抛光，即展现出晶体内所包裹的物质，直接欣赏原汁原味的水晶石。
