Not all crystals are equally crystalline. There will often be impurities, and the ionic & covalent concerning molecules can make vastly distinctive constructions outside of precisely the same materials. An awesome illustration of this are diamonds and graphene.

12He tried out again in several 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。

发晶的价值取决于发的颜色、罕见性及大小,一般是发色鲜艳、块度大的价格高。水胆水晶的价值主要取决于水胆及晶体的大小、透明度的高低。如果水胆较大并有一定形态,便可加工成较为珍贵的工艺品。另外水胆中的水也有一定的科学研究价值,通过它们可了解几百万年前地球上水的成分及变化。

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。

《全唐诗》卷七八五载《白雪歌》:“鸟啄冰潭玉镜开,风敲檐溜水晶折。”

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。

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。

⑤化学稳定�?非常好,在常温下仅溶解于氢氟酸,不溶解于其它各类酸、碱。在高温高压条件下可溶解于碳酸钠溶液中。

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。

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

This Critique chronicles above two decades of study into creating a genetic code for crystal engineering. As website an alternative to directing Organic processes, this code employs artificial kinds of DNA to programme the assembly of nanoparticles and microparticles into 1D, second and 3D crystalline architectures, in which just about every aspect of the resultant constructions might be systematically managed. Inside this conceptual framework, the structural and useful advances are explained in order to determine the current amount of sophistication and also to predict future Instructions of your System.

对于紫水晶黄水晶这样的单色水晶,通常要观察它的二色性,即使是最顶级的紫水晶黄水晶也是有色差的,通过这个方法可以鉴别是否加色。
