A solid is crystalline if it's long-assortment buy. Once the positions of an atom and its neighbours are recognized at just one issue, the spot of each atom is understood precisely through the crystal. Most liquids deficiency extended-range get, While numerous have short-range buy. Shorter variety is defined as the first- or next-closest neighbours of the atom. In lots of liquids the first-neighbour atoms are organized in the exact same construction as from the corresponding solid phase.
⒉棉、云雾或渣状包裹体、杂质在透明水晶内部有雾蒙蒙的现象或是感觉里面像有棉絮状、渣状物质一样的包裹体，这些包裹体的存在，影响水晶的整体美观。还有的水晶内局部含有黑斑或其他颜色的斑状物质，与水晶整体不协调，被视为水晶的杂质，有这种杂质的水晶是次品。
景观水晶，就是包裹体组成各种造型特异的水晶，有的似山水，有的似人物，有些像文字，有些像动物，植物，器物等等。
看原料：选料精良的水晶制品，应看不到胶口及棉絮；质地纯净、光润、晶莹为好。
Additionally, there are quite a few components that resemble crystals but are actually polycrystals. Polycrystals kind when microscopic crystals fuse together to sort a solid. These supplies tend not to include requested lattices.
Learn how the shape with the crystals identify the various minerals into familiesMinerals crystallize In line with one among seven motifs, often known as crystal programs.
石英：《广雅》称水晶叫石英，色白如莹者又叫白。为附的异形字。司马相如《子虚赋》就�?�?雌黄�?�?之句。苏林解释：�?�?，白石英�?”。
Ionic Crystals: Electrostatic forces type ionic bonds. A typical example can be a halite or salt crystal.
包裹体常见有固相、固液气三相组合、空洞以及双晶、色带等。水晶中典型的同生包裹体有自形的锐钛矿、气液两相包体等。
crystal The freshly crystallized quartz grains are characterized by elongate crystals oriented oblique to the shear band margins, defining an average grain-shape foliation. 来自 Cambridge English Corpus We are saying the chain topology inside the substantial w region acts as being the proverbial ' scratch-on-theglass ' essential within the natural and organic chemistry laboratory to help make crystals. 来自 Cambridge English Corpus The age scatter amid the individual crystals may well replicate incorporation of xenocrysts from earlier magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene types neutral to pale brown, subhedral to anhedral crystals, once in a while made up of inclusions of plagioclase microlaths and opaque phases.

The sodium Crystal chloride crystal lattice is characterised via the near packing on the optimistic sodium ions and adverse chloride ions. Every sodium ion is surrounded by six chloride ions, and every chloride ion is surrounded by 6 sodium ions, creating a really secure and symmetrical framework.
在透明的水晶中，隐裂纹呈亮晶晶的片状，有时还会有晕彩效应。这些裂纹是水晶在生长过程中，遇到外力挤压而在内部产生的一些隐形裂纹，隐裂纹在芙蓉石、紫水晶、白水晶球及白水晶柱中都很常见。有的裂纹后来被物质填充，形成愈合的裂纹，也就是原来的裂纹又长住了。这种裂纹对水晶的影响相对要小一些。
