The Definitive Guide to Crystal

李商隐，杜牧，白居易，欧阳修，苏轼，呈大昌，辛弃疾，杨万里，吴文英，杨基，魏源等诗坛，词林大家都有歌吟水晶的佳篇传世。

A elementary concept in crystal structures is definitely the device cell. It's the smallest unit of quantity that allows equivalent cells to generally be organized alongside one another to occupy all available Place. The geometrical basis of all crystals will be the lattice. A lattice may be considered as a daily and infinite arrangement of details or atoms, in which Each and every issue or atom has The same surrounding setting.

Chemical Bonds The categories of chemical bonds fashioned between atoms or groups of atoms in crystals depend upon their dimension and electronegativity. You will find 4 types of crystals as grouped by their bonding:

We have penned about in excess of 300 stones while in the mineral kingdom! Examine Every stone's exceptional origin, background, and energies down below.

这种水晶观赏石特指水晶晶簇，它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。

结晶�?When sea drinking water is allowed to evaporate, salt crystals are deposited. 海水蒸发后，盐的结晶体就沉淀下来。

水晶的评价标准和高端宝石有所不同。多数高端宝石把颜色放在评价的第一位，而对水晶来说，颜色和净度（水晶行业称作晶体）是近乎同等重要的因素：

市场上有很多人把熔炼水晶也叫做合成水晶，那是不准确的，一般都是以水晶废料为原料在高温高压下熔炼出来的，而不是结晶成的，不具备水晶的晶体特性，所以不能把熔炼水晶与合成水晶混为一谈；但是熔炼水晶耐高温，用优质二氧化硅熔炼成的熔炼水晶可以做成实用产品比如水晶杯、烤盘、茶具等，实际上一代伟人毛泽东主席的水晶棺就是选用东海优质水晶熔炼而成的。

13Nearly all personal computers have a quartz-crystal clock to control their Procedure.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。

Solids that have limited-assortment get but deficiency extensive-variety order are named amorphous. Practically any content might be created amorphous by swift solidification from the soften (molten point out). This condition is unstable, and also the stable will crystallize in time. In case the timescale for crystallization is decades, then the amorphous point out seems stable.

15The trick to a great thermoelectric product is a crystal structure through which electrons can flow freely.制造一种好的热电材料的关键是，需要一种电子可以自由流动的晶体结构。

You will discover only a few unique unit-cell styles, so many alternative crystals share a single device-cell type. A very important characteristic of the unit cell is the quantity of atoms it consists of. The overall amount of atoms in the entire crystal is definitely the variety in Every single mobile multiplied by the number of unit cells. Copper and aluminum (Al) Every single have a person atom for every Crystal device cell, while zinc (Zn) and sodium chloride have two. Most crystals have just a few atoms for every device cell, but there are some exceptions. Crystals of polymers, by way of example, have thousands of atoms in Every unit cell.

水晶饰品越来越受到人们的喜爱。中国、日本、韩国、美国等国家的人们还对水晶球情有独钟，喜欢将它们摆在家里或办公室里，认为水晶球有灵性，能保平安，带来财运。不过天然水晶不像看起来那么晶莹剔透，它也有瑕疵，我们在选购饰品的时候要注意。此外，我们还要掌握水晶的评价依据、选购方法，这样可以帮助我们在琳琅满目的水晶饰品中选到心仪的水晶。

水晶的价值根据品质、块体的大小、美感和产量多少的不同相差较大。遇到好的天然水晶要敢于下手，但好的水晶一般大家都想得到，值与不值，就要看经验了。由于天然水晶的开采和制作原因，没有瑕疵的水晶很难得到，纯净的饰品要达到与合成水晶媲美的品质，实在是很难得。另外，由于水晶的特性，在佩戴过程中，也会改变其等级，比如因为某种原因，有可能会逐渐产生较大裂纹。
