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。
Most good elements present in nature exist in polycrystalline form as an alternative to as an individual crystal. They are literally made up of numerous grains (smaller crystals) packed together to fill all House. Each and every individual grain has a special orientation than its neighbours. While extensive-assortment order exists inside a single grain, at the boundary among grains, the buying changes way. An average piece of iron or copper (Cu) is polycrystalline.
How Crystals Sort The process of forming a crystal is referred to as crystallization. Crystallization frequently occurs when a stable crystal grows from the liquid or Answer.
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。
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：

水晶的价值还与块体大小有关，同样的颜色和净度级别，块越大越难得。有时候质量级别虽然低一些，但块体够大，也可能价格高于高级别的小晶体
Crystals are labeled generally groups, for instance insulators, metals, semiconductors, and molecular solids. Just one crystal of an insulator is often clear and resembles a piece more info of glass. Metals are shiny Except they've rusted. Semiconductors are sometimes shiny and from time to time clear but are never rusty. Lots of crystals might be labeled as an individual sort of reliable, while some have intermediate behaviour. Cadmium sulfide (CdS) is often well prepared in pure sort and is a superb insulator; when impurities are additional to cadmium sulfide, it gets a fascinating semiconductor.
Tetragonal �?Characterised by 3 mutually perpendicular axes, two of which happen to be equal in size, although the third is for a longer time or shorter and perpendicular to the opposite two.
