This concept applies equally in one, two, and 3-dimensional Areas. Your entire crystal lattice can be made by frequently reproducing the pattern from the unit cell in all Instructions.
Yet another enjoyable, and tasty, experiment will be to form substantial crystals employing sugar. By heating sugar with water and after that allowing this Answer evaporate on sticks, you may sort rock sweet from sugar crystals!
水晶文化历史悠久,古人曾赋予它一串极富美感的雅称:水玉、水精、水碧、石英等。
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。
《全唐诗》卷七八五载《白雪歌》:“鸟啄冰潭玉镜开,风敲檐溜水晶折。”
Lattices could possibly have a single lattice place per cell or multiple, yielding a complete of 14 Bravais crystal lattice varieties. Bravais lattices, named for physicist and crystallographer Auguste Bravais, explain the 3-dimensional array made by a set of discrete factors.
对任何宝石来说,颜色都是非常重要的,水晶也不例外。如果是水晶晶体是有颜色的,如粉水晶、黄水晶、紫水晶等,其颜色评价的最高标准则是明艳动人,不带有灰色、黑色、褐色等其他色调。如粉水晶,颜色以粉红为佳;紫水晶,要求颜色为鲜紫,纯净不发黑;黄水晶,要求颜色不含绿色、柠檬色调,以金橘色为佳。对于发晶来说,晶体的颜色也是很重要的。相同发丝的金发晶,晶体完全无色(白水晶)和晶体略偏茶色,肉眼的视觉观感也是有差别的,所以前者的价格会高于后者。
Crystals may be developed under reasonable conditions from all ninety two In a natural way developing things except helium, and helium is usually crystallized at reduced temperatures by making use of 25 atmospheres of pressure.
13Nearly all computer systems include a quartz-crystal clock to regulate their operation.几乎所有的计算机都有一个石英晶体时钟来调节它们的运行。
Crystals with clear flat faces are referred to as euhedral crystals, when those lacking defined faces are termed anhedral crystals. Crystals consisting of ordered arrays of atoms that are not normally periodic are termed quasicrystals.

Crystals are categorised generally speaking classes, for instance insulators, metals, semiconductors, and molecular solids. Only one crystal of the insulator is normally clear and resembles a piece of glass. Metals are shiny unless they have got rusted. Semiconductors are occasionally shiny and occasionally clear but are hardly ever rusty. Lots of crystals could be labeled as one style of strong, while some have intermediate conduct. Cadmium sulfide (CdS) could be geared up in pure form and is an excellent insulator; when impurities are included to cadmium sulfide, it turns into an interesting semiconductor.
