This idea applies Similarly in one, two, and a few-dimensional Areas. All the crystal lattice might be created by continuously reproducing the sample of the device mobile in all directions.
按照透明度指标,水晶越透明,价格越高,好的透明的水晶加工出的成品晶莹剔透、光辉耀眼。透明度高的水晶能提升颜色的艳丽,否则显得呆板无灵性。光学水晶要求全透明、无双晶、无杂质。工艺水晶要求透明、少裂、少瑕疵。熔炼水晶要求透明,可有较多裂纹。三者价值依次降低,熔炼水晶只能作为熔炼水晶玻璃的原料。在工艺水晶中,晶体较大的,可用来做水晶眼镜和雕刻高档工艺品,因而价格较高。
A crystal framework concentrates on how the atoms are organized In the crystal. Even so, crystallographers are interested in the general shape and measurement from the crystal and its exterior qualities. To perform this, they should understand about the crystal process.
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。
看抛光:抛光的好坏直接影响到水晶制品的身价。抛光分为软抛光与硬抛光。
第二种是“半包裹体”,在水晶结晶以后,由于受到地球引力的影响而产生的裂隙,晶体外的一些物质通过水晶的裂隙渗透到水晶内部,一部分包裹于水晶之中另一部分露于水晶之外。我们可以看到物质渗进水晶的裂迹,常被称为“通道”,这种包裹体所形成的景象相对地较受自然环境和时间的影响,相应的价值也比较�?。

Hexagonal �?Characterised by 4 axes, a few of which happen to be equivalent in duration and intersect at 120 levels, that has a fourth axis perpendicular to one other three.
Metallic Crystals: Metals generally type metallic crystals, where a number of the valence electrons are absolutely free to maneuver through the entire lattice. Iron, by way of example, can variety unique metallic crystals.
晶体 Silicon crystals developed within a laboratory convert gentle into electrical Vitality. 在实验室中长成的硅晶体可将光线转变为电能。
地质学家目前为止对晶洞形成还没有广泛认同的理论,但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴,甚至动物挖的地洞。经过漫长时间,空腔的外壁变硬,溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间,缓慢渗入的矿物使得晶体在空腔内部结晶。

The composition in the sodium atoms by yourself, or maybe the chlorine atoms by itself, is fcc and defines the unit mobile. The sodium chloride construction So is built up of two interpenetrating fcc lattices. The cesium chloride lattice (Figure 3A) is based to the bcc framework; every other atom is cesium or chlorine. In this case, read more the device mobile can be a dice. The third crucial composition for AB
矿物成分:针铁矿、赤铁矿、金红石、磁铁矿、电气石、石榴石、云母、绿泥石等形成了包裹体水晶,如发晶、钛晶、绿幽灵等,发晶中则含有肉眼可见的似头发状的针状矿物的包裹体形成。含锰和铁者称紫水晶;含铁�?;呈金黄色或柠檬�?)称黄水晶;含锰和钛呈玫瑰色者称蔷薇石英,即粉水晶;烟色者称烟水晶;褐色者称茶晶;黑色透明者称为墨晶。
