The 5-Second Trick For Crystal

Not all crystals are equally crystalline. There are often impurities, and the ionic & covalent involving molecules can build vastly different buildings out of precisely the same substance. An excellent example of this are diamonds and graphene.

12He tried using again in many other metropolitan areas 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。

景观水晶,就是包裹体组成各种造型特异的水晶,有的似山水,有的似人物,有些像文字,有些像动物,植物,器物等等。

养殖晶:养殖晶是指,用天然水晶做种子,然后赋予天然水晶生长的高压条件,养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长,这样的水晶成分(分子式)与天然水晶是一摸一样的,唯一有差别的是,这样的水晶磁场作用没有天然水晶强。

There's also numerous components that resemble crystals but are literally polycrystals. Polycrystals variety when microscopic crystals fuse collectively to variety a sound. These elements don't encompass ordered lattices.

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。

根据包裹体和主晶宝石之间形成的先后关系可将水晶的包裹体划分以下三种类�?

Ionic Crystals: Electrostatic forces sort ionic bonds. A classic example is often a halite or salt crystal.

24I more info need to make my this means crystal obvious.我想把我的意思解释得清清楚楚。《牛津词典》

A crystal process refers to the classification of crystals based upon the geometric arrangement and symmetry of their lattice buildings. There are seven primary crystal methods:

用手去触摸水晶,天然水晶通常温度要比人造水晶的要凉的多;用眼观察,天然水晶通常有棉絮状的包裹体,这个是人造水晶所没有的。

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。

玉石纹理如果能形成美丽的花纹、图案,其价格就高,如玛瑙内红白相间的色带有规律地排列,形成缠丝玛瑙时,碧玉中的不均匀颜色形成一种风景图案时,材料的价值将提高。当水晶内包裹体形成美丽的图案时,如幽灵水晶、风景水晶,或者针状包裹体呈束状排列时,其价值都高于普通的水晶。图案越美观、越有意境越好。

Binary crystals are located in numerous constructions. Some pairs of things variety multiple structure. At home temperature, cadmium sulfide could crystallize possibly during the zinc blende or wurtzite structure. Alumina also has two doable structures at room temperature, α-alumina (corundum) and β-alumina. Other binary crystals show distinct buildings at distinctive temperatures. Among the most complex crystals are People of silicon dioxide (SiO2), that has 7 unique structures at a variety of temperatures and pressures; the most common of these buildings is quartz.
