Not all crystals are Similarly crystalline. There tend to be impurities, as well as ionic & covalent amongst molecules can build vastly distinctive constructions outside of precisely the same materials. An incredible example of this are diamonds and graphene.

12He tried using again in numerous other cities and succeeded with Crystal Caramels.他又在其他几个城市再次尝试,并成功制出了水晶焦糖。

一般而言,紫晶和黄晶是水晶中价值较高的品种。两者进一步的分级是据其颜色的深浅,颜色较深的为A级,稍浅的为B级。一般颜色较深的价格高,但要以不深暗为标准。颜色包括两种,一种是水晶本身的颜色,另一种是内部包裹体的颜色。水晶本身的颜色要艳丽、纯正,分布要均匀,不能太深或太浅,如澳州玉、蓝玉髓、紫晶、黄水晶,其价格就高。无色的水晶内含包裹体的颜色艳丽,其价格也高,如钛晶、绿幽灵、红兔毛。紫水晶一般以稍有云状物、颜色深紫、晶体通透的为上品。

The requested inside construction of enormous crystals, similar to the fluorite and quartz demonstrated listed here, is reflected in their geometric styles.

水胆水晶,包括气态,液态,固态,有时候可以同时多态并存,无色居多,个别情况下可见红色,绿色,黄色,蓝色,黑色等。

结晶�?When sea h2o is permitted 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:

11I cautiously opened the package and found a crystal bell inside.我小心地打开包裹,发现里面有一个水晶钟。

13Nearly all personal computers incorporate a quartz-crystal clock to control their operation.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。

A crystal process refers back to the classification of crystals based on the geometric arrangement and symmetry in their lattice structures. You will discover seven key crystal devices:

隐晶类水晶外观是一块块的,不是成六角水晶簇状,但他们却也是属六方晶系的。但我们不能以肉眼观察到他们的六角形结晶,因为结晶的体积极为细小,需以显微镜协助下才能看到六角开结晶。而此类水晶非常平滑,因为结晶之间有“水化硅石”填补,玛瑙便属于此类。

⑤、打孔:是在水晶成品未完成前,根据其所需打孔之尺寸及位置,以钻头加工,如制表件、笔筒、瓶孔等。

Binary crystals are located in quite a few buildings. Some pairs of things variety multiple construction. At space temperature, cadmium sulfide might crystallize either from the zinc blende or wurtzite composition. Alumina also has two achievable constructions at space temperature, α-alumina (corundum) and β-alumina. Other binary crystals show distinctive constructions at unique temperatures. Amongst the most elaborate crystals are People of silicon dioxide (SiO2), which has 7 distinct buildings at numerous temperatures and pressures; the most typical of get more info these constructions is quartz.
