A strong is crystalline if it's long-array buy. When the positions of the atom and its neighbours are recognised at one particular position, the spot of each atom is thought precisely through the crystal. Most liquids absence extended-assortment purchase, Whilst many have short-array buy. Shorter variety is described as the first- or next-closest neighbours of an atom. In lots of liquids the very first-neighbour atoms are arranged in precisely the same structure as in the corresponding strong phase.
12He experimented with all over again in several other cities and succeeded with Crystal Caramels.他又在其他几个城市再次尝试，并成功制出了水晶焦糖。
Chemical Bonds The types of chemical bonds formed among atoms or groups of atoms in crystals rely upon their measurement and electronegativity. There are actually 4 categories of crystals as grouped by their bonding:
Fig. seven: A template-directed technique can Regulate the placement of constructing blocks on the floor within the formation of elaborate buildings.
水胆水晶，包括气态，液态，固态，有时候可以同时多态并存，无色居多，个别情况下可见红色，绿色，黄色，蓝色，黑色等。
结晶�?When sea h2o is permitted to evaporate, salt crystals are deposited. read more 海水蒸发后，盐的结晶体就沉淀下来。
根据包裹体和主晶宝石之间形成的先后关系可将水晶的包裹体划分以下三种类�?
②固体包裹体：指呈固态相存在包裹体，多因岩浆、热液、变质作用等形成的早期结晶物被水晶捕获而形成。
仿制钛晶树水晶：钛晶是水晶里价格最昂贵的，造假者当然也不会放过这么好的产品。天然的环境下，在水晶里能生长个像树一样的钛晶，完全是可能的，只是这样的货很少，那我们的造假专家是如何做的呢，白水晶底下打个洞，激光打点成板状的钛晶进去，就这样这块水晶的身价就能飙升几十倍。往往有的钛晶戒面，会采用将钛晶部位割成板状，与圆面的水晶粘合的方法来制作。
看文化：水晶里面的包裹体象形，能与文化、宗教及历史有所牵连的话，价格往往会比水晶本身的价值高出几倍甚至几百倍。
用手去触摸水晶，天然水晶通常温度要比人造水晶的要凉的多；用眼观察，天然水晶通常有棉絮状的包裹体，这个是人造水晶所没有的。
Crystallography may be the study of crystals, and it promotions with everything from best geometric shapes to seemingly random conglomerations of particles and minerals.
水玉：中国最古老的称法叫水玉，意谓似水之玉，又说是 �?千年之冰所�?�?。唐代诗人温庭筠《题李处士幽居》写道：�?水玉簪头白角巾，瑶琴寂历拂轻�?”。水玉一词最早频繁出于《山海经》：�?又东三百里，日堂庭之�?…�?多水�?”；�?丹山出焉，东南流注于洛水，其中多水玉 ”；�?逐水出焉，北流注于渭，其中多水玉 ”。司马相如《上林赋》曰�?�?水玉磊河 �?。水晶得名水玉，古人是看�?�?其莹如水，其坚如�?�?的质地。
The C60 molecules, also referred to as buckyballs, are very strong and Just about incompressible. Crystals are shaped this sort of which the balls are arranged in an fcc lattice that has a just one-nanometre spacing among the centres of adjacent balls. The similar C70 molecule has the shape of the rugby ball; C70 molecules also variety an fcc crystal when stacked with each other. The stable fullerenes variety molecular crystals, with weak binding—supplied by van der Waals interactions—amongst the molecules.
