A stable is crystalline if it's got extensive-range purchase. Once the positions of the atom and its neighbours are known at a person point, the place of every atom is thought exactly through the entire crystal. Most liquids absence very long-array order, Despite the fact that many have short-vary get. Limited assortment is described as the 1st- or next-closest neighbours of the atom. In lots of liquids the primary-neighbour atoms are organized in the exact same construction as inside the corresponding stable phase.
the strong point out of many very simple substances, which have a daily form and surfaces organized in equivalent patterns
10This is the silicon chip—a little bit chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
Large crystals of diamond are valuable gemstones. The crystal has other fascinating Attributes; it has the highest sound velocity of any strong and is the best conductor of heat. Apart from diamond, the other common kind of carbon is graphite, that's a layered substance. Just about every carbon atom has 3 coplanar in close proximity to neighbours, forming an arrangement known as the honeycomb lattice. A few-dimensional graphite crystals are obtained by stacking identical levels.
C2 [ U ] clear glass of really superior quality, commonly with its surface area Lower into delicate designs:
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�?。
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 are very little more than an requested arrangement of molecules or atoms. Crystals can be found in many different styles and sizes, and each has unique features. What they are created of decides how it'll sort.
第三种是“皮景”，因某些其他的矿物与水晶体共生，或由于其他的物质侵蚀而依附于水晶表面，或者是水晶受自然环境的影响，在水晶表面出现蚀象，形成了一些景象或图案，这种景观存在于水晶表面。
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 within the figure. It's exactly the same aircraft-triangular construction; the atoms sit during the holes fashioned by the 1st layer. The main layer has two equivalent sets of holes, nevertheless the atoms of the 2nd layer can occupy only one established. The third layer, labeled C
There are other minerals and molecules that could kind these crystal lattices. Snowflakes are a typical illustration of a roughly symmetric and geometrically patterned structure from ice crystals, and gemstones of all types are typically crystals.
crystal, any reliable materials by which the ingredient atoms are organized inside of a definite pattern and whose surface regularity displays check here its internal symmetry.
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。
