This concept applies equally in one, two, and 3-dimensional spaces. The complete crystal lattice might be manufactured by consistently reproducing the pattern from the unit cell in all Instructions.
Bismuth (Bi) appears to get a metal, but the volume of electrons accessible for electrical conduction is analogous to that of semiconductors. In actual fact, bismuth is termed a semimetal. Molecular solids usually are crystals fashioned from molecules or polymers. They may be insulating, semiconducting, or metallic, depending upon the type of molecules from the crystal. New molecules are continually staying synthesized, and many are made into crystals. The amount of different crystals is enormous.
结晶的形状非常细小，需要用显微镜才能看得清楚，外观上看起来是平滑、块状。常见最多的是各式玛瑙
Encyclopaedia Britannica's editors oversee subject matter regions where they've got comprehensive know-how, no matter whether from many years of experience obtained by engaged on that content material or through review for an advanced diploma. They write new written content and confirm and edit material been given from contributors.
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。
第二种是“半包裹体”，在水晶结晶以后，由于受到地球引力的影响而产生的裂隙，晶体外的一些物质通过水晶的裂隙渗透到水晶内部，一部分包裹于水晶之中另一部分露于水晶之外。我们可以看到物质渗进水晶的裂迹，常被称为“通道”，这种包裹体所形成的景象相对地较受自然环境和时间的影响，相应的价值也比较�?。

损伤是指水晶由于加工或不小心摔掉、碰撞等原因，人为造成的损坏。它可以是破口，也可以是凹坑等。
Crystals tend to be considered as a thing of enormous elegance, they usually are commonly made use of with diamonds or other stones to help make pieces of jewelry. Virtually all crystals now are man-designed in laboratories.
crystal The recently crystallized quartz grains are characterised by elongate crystals oriented oblique to your shear band margins, defining an average grain-shape foliation. 来自 Cambridge English Corpus We are saying the chain topology while in the large w area acts given that the proverbial ' scratch-on-theglass ' essential within the natural chemistry laboratory to generate crystals. 来自 Cambridge English Corpus The age scatter amongst the person crystals may replicate incorporation of xenocrysts from previously magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene sorts neutral to pale brown, subhedral to anhedral crystals, sometimes that contains inclusions of plagioclase microlaths and opaque phases.
15The trick to a very good thermoelectric product is often a crystal structure in which electrons can stream freely.制造一种好的热电材料的关键是，需要一种电子可以自由流动的晶体结构。
You can find just a few unique unit-cell designs, so a number of crystals share Crystal one device-cell sort. A very important characteristic of the device mobile is the quantity of atoms it contains. The full amount of atoms in all the crystal is definitely the range in Every single cell multiplied by the quantity of unit cells. Copper and aluminum (Al) Every have a person atom for every unit mobile, although zinc (Zn) and sodium chloride have two. Most crystals have only a few atoms for each device mobile, but there are many exceptions. Crystals of polymers, as an example, have 1000s of atoms in Every device mobile.
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。
水晶观赏石是天然水晶中最具代表的作品，具有其他宝石都不具备的观赏性。不论是玉石翡翠还是都要经过雕琢后次能体现他的价值，而水晶观赏石只需要将表面进行抛光，即展现出晶体内所包裹的物质，直接欣赏原汁原味的水晶石。
