Calcite crystals are sometimes Utilized in optical products, as well as the graphite in pencil guide are sheets of crystals that fundamentally crack aside layer by layer to jot down. Silica can form silicate crystals which can be the basis for quartz, mica, olivine, and many other crystals and minerals.

Bismuth (Bi) appears to be a steel, but the number of electrons obtainable for electrical conduction is similar to that of semiconductors. The truth is, bismuth is called a semimetal. Molecular solids tend to be crystals shaped from molecules or polymers. They may be insulating, semiconducting, or metallic, with regards to the sort of molecules inside the crystal. New molecules are continually currently being synthesized, and lots of are created into crystals. The volume of diverse crystals is gigantic.

10This is definitely the silicon chip—just a little chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。

③次生包裹体：指主体水晶形成后，由于环境的变化使得主晶周围的一些物质沿裂隙进入到其内部而形成的包裹体。形成的原因有出熔作用、裂隙的结晶化、以及放射性元素破坏的作用等。水晶典型的次生包裹体有胶花水晶中的氧化铁充填物等。

2She was donning a strand of crystal beads.她戴着一串水晶珠子。《柯林斯英汉双解大词典》

Lattices may have one lattice stage for each cell or multiple, yielding a total of 14 Bravais crystal lattice types. Bravais here lattices, named for physicist and crystallographer Auguste Bravais, explain the a few-dimensional array made by a set of discrete details.

⑩、雷射内雕：以计算机辅助激光设备在水晶对象中进行三维图案的成型，艺术效果好，可以任意表达各类图案，图形，达到逼真效果

Crystals is usually grown underneath average situations from all ninety two naturally developing elements besides helium, and helium is often crystallized at very low temperatures by making use of twenty five atmospheres of force.

水晶常以晶簇、晶洞形式产出，其中水晶洞一般存在于由火山喷发而形成的巨厚熔岩流层的火成岩与玄武岩中。火山喷发时所含的气体或热水溶蚀等作用导致岩层中出现大量的孔隙，当富含硅质矿物的流体进入较薄的熔岩孔隙中，且温、压条件合适时将结晶沉淀出水晶等矿物。

⑤化学稳定�?非常好，在常温下仅溶解于氢氟酸，不溶解于其它各类酸、碱。在高温高压条件下可溶解于碳酸钠溶液中。

. The 2nd layer is shaded from the determine. It's got the exact same aircraft-triangular framework; the atoms sit while in the holes fashioned by the first layer. The primary layer has two equivalent sets of holes, however the atoms of the next layer can occupy just one established. The third layer, labeled C

The sodium chloride crystal lattice is characterized via the shut packing of your beneficial sodium ions and unfavorable chloride ions. Each sodium ion is surrounded by six chloride ions, and every chloride ion is surrounded by six sodium ions, developing a very stable and symmetrical composition.

This Evaluate chronicles about twenty years of study into creating a genetic code for crystal engineering. Rather than directing Organic procedures, this code uses synthetic kinds of DNA to programme the assembly of nanoparticles and microparticles into 1D, 2D and 3D crystalline architectures, in which almost each aspect of the resultant structures may be systematically controlled. Within this conceptual framework, the structural and useful advancements are explained in an effort to outline the existing degree of sophistication and to forecast future Instructions with the platform.

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。
