A stable is crystalline if it has very long-assortment purchase. As soon as the positions of an atom and its neighbours are identified at just one point, the place of each and every atom is understood specifically through the crystal. Most liquids absence extensive-range order, although quite a few have quick-vary get. Small selection is outlined as the first- or next-nearest neighbours of the atom. In several liquids the primary-neighbour atoms are arranged in precisely the same construction as during the corresponding reliable period.
23Sometimes, on the other hand, the crystal kind of the silicate inclusions is observed to resemble far more carefully 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。
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。
养殖晶：养殖晶是指，用天然水晶做种子，然后赋予天然水晶生长的高压条件，养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长，这样的水晶成分（分子式）与天然水晶是一摸一样的，唯一有差别的是，这样的水晶磁场作用没有天然水晶强。
C2 [ U ] clear glass of quite high quality, commonly with its floor Slice into delicate patterns:
, has a similar framework, but there are two possibilities for selecting the holes the atoms will occupy. The third layer is often placed in excess of the atoms of the very first layer, making an alternate layer sequence A
Crystals glance exclusive from all kinds of other rocks and minerals, but �?barring some Particular situations �?nearly all minerals hide a crystalline structure underneath the surface area.
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。
Many crystals behave like butter in that they are hard at reduced temperatures but delicate at larger temperatures. They may be called solids in the least temperatures underneath their melting position. A doable definition of the solid is surely an object that retains its condition if left undisturbed. The pertinent challenge is how much time the item keeps its condition. A extremely viscous fluid retains its condition for an hour or so although not a yr. A good have to maintain its form more time than that.

Crystal Lattices There are actually 7 methods of crystal structures, that are also called lattices or Place lattices:
⑨、喷砂：立体感弱，较平整，无凹凸感，机器雕刻文字、图形等后进行效果处理。成本低制作快。
crystal Alteration is variable: absent in many crystals, in Many others generating dense sericite aggregates which can demonstrate some recrystallization consequences to generate coarser-grained white mica. From the Cambridge English Corpus The tridymite crystals are rectangular or wedge-shaped and are sometimes organized in aggregates. With the Cambridge English Corpus Also, haloarchaeal cells were being embedded inside of salt crystals beneath laboratory ailments and subsequently analysed by light-weight microscopy. From the Cambridge English Corpus The white clouds (commonly sparse) have been also commonly viewed as remaining made up of small crystals of h2o ice, relatively like cirrus in our environment. In the Cambridge English Corpus They are really present in evaporite salt lakes and will be trapped in salt crystals in the course of evaporation. Through the Cambridge English Corpus Hence, the cells (organelles and membranes) are wrecked mechanically by ice crystals, leading to Demise by means of mobile lysis. With the Cambridge English Corpus The crystals have been Utilized in the 1st or second orders of reflection. In the Cambridge English Corpus Inside our 8xperiments, the crystals were being cubes that has a foundation spot of eight e mm. With the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : outcome of temperature and stress.
