A solid is crystalline if it's got extended-variety order. When the positions of an atom and its neighbours are regarded at a person stage, the position of each atom is understood exactly all over the crystal. Most liquids absence very long-range purchase, Though numerous have small-range purchase. Small vary is outlined as the 1st- or 2nd-closest neighbours of an atom. In many liquids the very first-neighbour atoms are arranged in the identical structure as while in the corresponding reliable period.

10This will be the silicon chip—a little bit chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
③次生包裹体：指主体水晶形成后，由于环境的变化使得主晶周围的一些物质沿裂隙进入到其内部而形成的包裹体。形成的原因有出熔作用、裂隙的结晶化、以及放射性元素破坏的作用等。水晶典型的次生包裹体有胶花水晶中的氧化铁充填物等。
How Crystals Kind The entire process of forming a crystal is called crystallization. Crystallization typically occurs every time a stable crystal grows from a liquid or solution.
Not all crystals kind in drinking water, but almost all crystals sort the same way, atoms appear with each other and become a uniformed cluster. The procedure may take as minimal as a few days to maybe a thousand yrs. Purely natural crystals that come from the Earth form the exact same way.

Like a sizzling solution cools or even a saturated Alternative evaporates, particles attract shut more than enough for chemical bonds to kind. Crystals also can check here form from deposition straight from the gas stage. Liquid crystals possess particles oriented in an arranged fashion, like strong crystals, nonetheless can stream.
水晶常以晶簇、晶洞形式产出，其中水晶洞一般存在于由火山喷发而形成的巨厚熔岩流层的火成岩与玄武岩中。火山喷发时所含的气体或热水溶蚀等作用导致岩层中出现大量的孔隙，当富含硅质矿物的流体进入较薄的熔岩孔隙中，且温、压条件合适时将结晶沉淀出水晶等矿物。
Crystals with obvious flat faces are known as euhedral crystals, when those missing described faces are referred to as anhedral crystals. Crystals consisting of ordered arrays of atoms that are not generally periodic are named quasicrystals.

隐晶类水晶外观是一块块的，不是成六角水晶簇状，但他们却也是属六方晶系的。但我们不能以肉眼观察到他们的六角形结晶，因为结晶的体积极为细小，需以显微镜协助下才能看到六角开结晶。而此类水晶非常平滑，因为结晶之间有“水化硅石”填补，玛瑙便属于此类。
玉石纹理如果能形成美丽的花纹、图案，其价格就高，如玛瑙内红白相间的色带有规律地排列，形成缠丝玛瑙时，碧玉中的不均匀颜色形成一种风景图案时，材料的价值将提高。当水晶内包裹体形成美丽的图案时，如幽灵水晶、风景水晶，或者针状包裹体呈束状排列时，其价值都高于普通的水晶。图案越美观、越有意境越好。
The C60 molecules, also known as buckyballs, are fairly solid and Nearly incompressible. Crystals are shaped this sort of the balls are organized in an fcc lattice with a one particular-nanometre spacing in between the centres of adjacent balls. The comparable C70 molecule has The form of the rugby ball; C70 molecules also variety an fcc crystal when stacked together. The good fullerenes kind molecular crystals, with weak binding—provided by van der Waals interactions—in between the molecules.
