天然的水晶一般都会有絮状（绵绺），也就是大家俗称的瑕疵，这是液体水落石出和二氧化碳的小孔穴，而人工合成的水晶就不会有这样的特征。
Bismuth (Bi) appears to become a steel, but the amount of electrons obtainable for electrical conduction is analogous to that of semiconductors. In fact, bismuth known as a semimetal. Molecular solids are frequently crystals formed from molecules or polymers. They may be insulating, semiconducting, or metallic, based on the kind of molecules in the crystal. New molecules are continually being synthesized, and a lot of are created into crystals. The number of distinct crystals is big.
天然水晶是不可再生资源，随着开发的深入，天然水晶存量已越来越少，为了可持续发展，东海县政府早就制定了保护本地资源，鼓励开发海外水晶资源的政策，但是，海外资源也越来越少，很多国家都提高了开采和出口天然水晶的门槛，进入东海市场的外国水晶价格连年暴涨，其中观赏水晶比普通水晶涨价更快。
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。
这种水晶观赏石特指水晶晶簇，它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。
, has precisely the same framework, but there are two decisions for choosing the holes that the atoms will occupy. The third layer might be positioned about the atoms of the first layer, building an alternate layer sequence A
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。
水晶包裹体丰富多彩，从气体、液体到各种矿物质，甚至宝石，均可被包含于水晶内，各种包裹体所形成的景象更是变化万千。按照包裹体的内容，常把包裹体水晶分为一下八类：
The definition of a solid appears apparent; a sound is generally considered staying really hard and agency. On inspection, nonetheless, the definition gets much less easy. A cube of butter, such as, is hard right after becoming stored in the refrigerator and is Plainly a stable. Just after remaining to the kitchen counter for on a daily basis, the exact same dice turns into quite tender, and it really is unclear When the butter need to nevertheless be regarded as a solid.
Single crystals of metals are smooth and malleable, even though polycrystalline metals are harder and more powerful and are more handy industrially. Most polycrystalline materials could be produced into substantial solitary crystals following extended heat treatment. Before blacksmiths would heat a bit of metallic to really make it malleable: heat helps make a couple of grains develop massive by incorporating smaller sized ones. The smiths would bend the softened steel into shape and then pound it awhile; the pounding would make it polycrystalline all over again, raising its power.
Crystals are not only renowned for his or her Bodily visual appearance, but diverse crystals of various elements and formations may result in an enormous a number of uses and Actual physical properties.
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。
crystal Alteration is variable: absent in lots of crystals, in Other folks Crystal creating dense sericite aggregates which may display some recrystallization outcomes to provide coarser-grained white mica. Within the Cambridge English Corpus The tridymite crystals are rectangular or wedge-shaped and are occasionally arranged in aggregates. Within the Cambridge English Corpus Additionally, haloarchaeal cells had been embedded inside of salt crystals below laboratory situations and subsequently analysed by light microscopy. From the Cambridge English Corpus The white clouds (generally sparse) had been also greatly viewed as currently being made up of tiny crystals of h2o ice, instead like cirrus in our ambiance. With the Cambridge English Corpus They can be present in evaporite salt lakes and may be trapped in salt crystals for the duration of evaporation. Within the Cambridge English Corpus Therefore, the cells (organelles and membranes) are wrecked mechanically by ice crystals, bringing about death via mobile lysis. From your Cambridge English Corpus The crystals have been Employed in the 1st or next orders of reflection. Through the Cambridge English Corpus Inside our 8xperiments, the crystals were cubes which has a base spot of 8 e mm. Within the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : effect of temperature and stress.
