Crystals are lovely rock formations which have surprised individuals for A large number of a long time. They are utilized for several various things, not only for decoration. Most of the first radios ever invented made use of crystals to transmit the radio waves. Some devices, like quartz watches and laser crystals, use Exclusive Qualities and harmonic abilities of crystals for making very correct measurements and adjustments.
A basic concept in crystal structures could be the unit mobile. It is the smallest unit of volume that permits identical cells to be stacked with each other to fill all Area. By repeating the sample on the device mobile repeatedly in all directions, the whole crystal lattice can be created. A cube is The best illustration of a device cell. Two other examples are revealed in Figure 1. The initial is the unit mobile for the encounter-centred cubic lattice, and the next is to get a body-centred cubic lattice. These constructions are discussed in the subsequent paragraphs.
Encyclopaedia Britannica's editors oversee topic spots in which they may have considerable information, no matter whether from a long time of encounter acquired by focusing on that articles or by using review for a complicated here diploma. They publish new content and confirm and edit content material gained from contributors.
2She was carrying a strand of crystal beads.她戴着一串水晶珠子。《柯林斯英汉双解大词典》
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。
光泽：玻璃光泽。断口处为油脂光泽。光泽，指宝石表面对光线反射的一种光学性质。观察水晶的光泽，可用手握着它，以灯光或窗户投进来的光线看表面反射，透明水晶亮度与光泽强弱有关。
Crystals might be developed beneath reasonable ailments from all 92 The natural way transpiring elements apart from helium, and helium is often crystallized at very low temperatures through the use of twenty five atmospheres of pressure.
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。
晶体 Silicon crystals developed inside a laboratory convert gentle into electrical energy. 在实验室中长成的硅晶体可将光线转变为电能。

Crystals are categorized usually groups, including insulators, metals, semiconductors, and molecular solids. Just one crystal of an insulator is normally transparent and resembles a bit of glass. Metals are shiny Until they've rusted. Semiconductors are sometimes shiny and often clear but are under no circumstances rusty. Lots of crystals may be classified as a single type of reliable, while others have intermediate behaviour. Cadmium sulfide (CdS) may be geared up in pure type and is an excellent insulator; when impurities are extra to cadmium sulfide, it turns into an interesting semiconductor.
Binary crystals are present in many structures. Some pairs of features form more than one structure. At space temperature, cadmium sulfide may crystallize possibly in the zinc blende or wurtzite structure. Alumina also has two probable constructions at place temperature, α-alumina (corundum) and β-alumina. Other binary crystals exhibit distinctive structures at diverse temperatures. Among the many most advanced crystals are Those people of silicon dioxide (SiO2), that has seven distinctive constructions at various temperatures and pressures; the most common of those structures is quartz.
