Calcite crystals tend to be used in optical products, and perhaps the graphite in pencil direct are sheets of crystals that primarily break aside layer by layer to jot down. Silica can type silicate crystals which happen to be The premise for quartz, mica, olivine, and all kinds of other crystals and minerals.
Crystals are lovely rock formations that have surprised human beings for Countless yrs. They are really useful for several various things, not just for decoration. A lot of the first radios ever invented utilized crystals to transmit the radio waves. Some instruments, like quartz watches and laser crystals, use Exclusive properties and harmonic abilities of crystals to produce very exact measurements and adjustments.
人造水晶分为熔炼水晶与养殖晶：据水晶专家汪毅的阐述，随着水晶的价值提高，喜欢的人增多，水晶也引起了作伪者的兴趣，现阶段中国水晶市场常见的造假方法为：
Fig. three: A library of lattice symmetries is usually accessed by switching the particle Main and DNA shell.
. These 4 structures comprise a lot of the binary crystals with equal quantities of cations and anions.
你们都知道，拿起一个水晶棱镜，让一束阳光通过它，就会得到一个光谱，看起来就像一条连续的彩虹色带。
⑦、镀彩：运用类似电镀的手法在水晶表面以不同的色彩，层面较薄，经摩擦可划伤�?；出现划痕，由于镀彩经常位于底部，因此在镀彩底部经常采用其它对象附着，如生肖文镇。
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。
水晶包裹体丰富多彩，从气体、液体到各种矿物质，甚至宝石，均可被包含于水晶内，各种包裹体所形成的景象更是变化万千。按照包裹体的内容，常把包裹体水晶分为一下八类：
多色�?无色水晶没有多色性。有色水晶有弱到强的多色�?表现为体色的不同深浅。
The basic units of solids are possibly atoms or atoms that have blended into molecules. The electrons of an atom move in orbits that kind a shell structure within the nucleus. The shells are filled in a scientific order, with Just about every shell accommodating only a little range of electrons. Diverse atoms have different figures of electrons, which happen to be dispersed inside a attribute Digital structure of filled and partly stuffed shells.

《古今小说·李公子救蛇获称心》：“器皿皆是玻璃、水晶、琥珀、玛瑙为之，曲尽巧妙，非人间所有。”
A further type of crystalline carbon is based on a molecule with sixty carbon atoms termed buckminsterfullerene (C60). The molecular form is spherical. Every carbon is bonded to three neighbours, as in graphite, plus the spherical form is obtained by a mix of twelve rings with 5 sides and twenty rings with 6 sides. Identical structures were being first visualized with the American architect R. Buckminster Fuller for geodesic domes.
