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 essential strategy in crystal structures could be the device mobile. It is the smallest unit of volume that permits similar cells to become arranged jointly to occupy all offered Area. The geometrical foundation of all crystals is the lattice. A lattice is often considered as a daily and infinite arrangement of factors or atoms, where by each place or atom has A similar surrounding setting.
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。
Tetragonal: These crystals type prisms and double pyramids. The construction is sort of a cubic crystal, besides just one axis is for a longer period than the other.
How Crystals Form The entire process of forming a crystal is known as crystallization. Crystallization typically takes place each time a solid crystal grows from the liquid or Option.
无色水晶与无色长石因折射率和密度十分接近故较难区分。主要方法是放大检查。长石有两组极完全解理，显微镜下可见两组解理相交而成的“娱蛤状”包裹体或细直的纹理，而水晶则无解理发育，仅有时可见断续不规则的裂理。
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。
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。
Crystals are often seen as some thing of huge elegance, plus they are commonly applied with diamonds or other stones to generate pieces of jewellery. Nearly all crystals now are guy-created in laboratories.
A crystal method refers back to the classification of crystals based upon the geometric arrangement and symmetry in their lattice constructions. You can find seven main crystal programs:
There's two these types of doable periodic arrangements. In Each and every, the primary layer has the atoms packed into a plane-triangular lattice in which each atom has 6 immediate neighbours. Figure 2 demonstrates this arrangement for the atoms labeled A
国家还并未给天然水晶提供一个等级划分的具体标准，水晶品种繁杂，每一品种都有他不同的评判标准。
⑦双色水晶：一种紫色和黄色共存一体的水晶，紫色、黄色之间界限较明显，分别占据晶块的一部分。
Tetragonal �?Characterised check here by 3 mutually perpendicular axes, two of which happen to be equal in size, whilst the 3rd is for a longer period or shorter and perpendicular to another two.
