Not all crystals are Similarly crystalline. There will often be impurities, and the ionic & covalent involving molecules can generate vastly various constructions out of a similar content. A terrific illustration of this are diamonds and graphene.

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
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。
看抛光：抛光的好坏直接影响到水晶制品的身价。抛光分为软抛光与硬抛光。
Lattices may have a person lattice issue for each mobile or multiple, yielding a complete of fourteen Bravais crystal lattice types. Bravais lattices, named for physicist and crystallographer Auguste Bravais, explain the three-dimensional array produced by a list of discrete factors.
Springer Mother nature remains neutral with regards to jurisdictional claims in published maps and institutional affiliations.
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 are labeled usually classes, for example insulators, metals, semiconductors, and molecular solids. A single crystal of an insulator is usually transparent and resembles a bit of glass. Metals are shiny Except if they have got rusted. Semiconductors are sometimes shiny and occasionally clear but are by no means rusty. Several crystals might be classified as a single sort of stable, while some have intermediate conduct. Cadmium sulfide (CdS) can be organized in pure variety and is a wonderful insulator; when impurities are extra to cadmium sulfide, it results in being a fascinating semiconductor.
crystal Alteration is variable: absent in lots of crystals, in Other people producing dense sericite aggregates which can display some recrystallization consequences to supply coarser-grained white mica. With the Cambridge English Corpus The tridymite crystals are rectangular or wedge-shaped and are occasionally organized in aggregates. From your Cambridge English Corpus Additionally, haloarchaeal cells have been embedded in salt crystals beneath laboratory conditions and subsequently analysed by gentle microscopy. From the Cambridge English Corpus The white clouds (generally more info sparse) ended up also greatly regarded as currently being composed of little crystals of h2o ice, alternatively like cirrus in our environment. From your Cambridge English Corpus They are really found in evaporite salt lakes and might be trapped in salt crystals throughout evaporation. With the Cambridge English Corpus As a result, the cells (organelles and membranes) are wrecked mechanically by ice crystals, leading to Loss of life via mobile lysis. From the Cambridge English Corpus The crystals have been Employed in the main or second orders of reflection. Through the Cambridge English Corpus Within our 8xperiments, the crystals had been cubes which has a foundation area of 8 e mm. Through the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : result of temperature and force.
