8Where can we get this magic wand and crystal ball?我们到哪里获得这种魔棒和水晶玻璃球？
Another pleasurable, and tasty, experiment is to type substantial crystals using sugar. By heating sugar with h2o and afterwards letting this solution evaporate on sticks, you'll be able to type rock candy from sugar crystals!
4Without a crystal ball, it's impossible to say in which we will be next year.不用水晶球预卜未来，我们说不准明年处境如何呀。《牛津词典》
Most reliable materials present in nature exist in polycrystalline type as an alternative to as an individual crystal. They are literally made up of many grains (small crystals) packed with each other to fill all House. Every single unique grain has another orientation than its neighbours. Though long-selection purchase exists within a single grain, in the boundary in between grains, the ordering variations path. An average bit of iron or copper (Cu) is polycrystalline.
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。
Encyclopaedia Britannica's editors oversee subject matter places in which they have comprehensive understanding, regardless of whether from several years of practical experience received by focusing on that content material or via analyze for an advanced diploma. They compose new content material and verify and edit material obtained from contributors.
水晶内部有多种矿物包裹体，形成的各种景观可以肉眼观测，这样的水晶就是包裹体水晶观赏石。由于水晶本身就是宝石，因此人们称誉包裹体水晶为“宝石级的观赏石”。包裹体水晶观赏石都具有独特性，具有极高欣赏和收藏价值。
市场上有很多人把熔炼水晶也叫做合成水晶，那是不准确的，一般都是以水晶废料为原料在高温高压下熔炼出来的，而不是结晶成的，不具备水晶的晶体特性，所以不能把熔炼水晶与合成水晶混为一谈；但是熔炼水晶耐高温，用优质二氧化硅熔炼成的熔炼水晶可以做成实用产品比如水晶杯、烤盘、茶具等，实际上一代伟人毛泽东主席的水晶棺就是选用东海优质水晶熔炼而成的。
Among the binary crystals, the best constructions to visualize are Individuals with equal figures of The 2 varieties of atoms. The composition of sodium chloride relies on a dice. To build the lattice, the sodium and chlorine atoms are placed on alternate corners of a cube, and also the framework is recurring (Determine 3B).
Solids that have quick-variety order but lack prolonged-selection purchase are identified as amorphous. Virtually any materials can be built amorphous by fast solidification through the soften (molten state). This problem is unstable, as more info well as the good will crystallize in time. When the timescale for crystallization is several years, then the amorphous state appears stable.
. The next layer is shaded from the figure. It's got exactly the same airplane-triangular construction; the atoms sit during the holes shaped by the main layer. The 1st layer has two equivalent sets of holes, nevertheless the atoms of the 2nd layer can occupy only one established. The third layer, labeled C
The sodium chloride crystal lattice is characterized through the shut packing from the beneficial sodium ions and adverse chloride ions. Each sodium ion is surrounded by six chloride ions, and each chloride ion is surrounded by six sodium ions, creating a hugely stable and symmetrical structure.
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。
⑥白色的包裹体有蚀变的绿泥石、云母、愈合裂隙、水晶、方解石、透闪石等。
