其它描述:《庶物异名疏》中说: �?水精出大秦国,一名黎�?�?。结晶完整的水晶晶体,就如参差交错的马齿,所以人们又叫它马牙石。先民们最早用它研磨成眼镜片,因而送它一个眼镜石的绰号。水晶有通称,也有俗称。广州一带称水晶叫晶玉,又名鱼脑冻;江苏东海县山民发现水晶会 �?窜火�?�?,于是给它起个放光石的俗名。世间一物多名,不足为奇,而像水晶拥有这么多的别称,实不多见。瞧,从水玉、水碧、白玉、玉瑛、水精石英、黎难、晶玉到菩萨石、马牙石、眼镜石、放光石、千年冰、高山冻、鱼脑冻等等,简直构成一部奇石鉴赏史。
23Sometimes, even so, the crystal method of the silicate inclusions is observed to resemble a lot more carefully the internal composition of diamond than that of other silicate minerals.然而,有时观察到硅酸盐包裹体的晶体形态比其他硅酸盐矿物更接近金刚石的内部结构。
A crystal framework focuses on how the atoms are arranged In the crystal. Nevertheless, crystallographers have an interest in the general form and size on the crystal along with its exterior qualities. To perform this, they should learn about the crystal method.
看原料:选料精良的水晶制品,应看不到胶口及棉絮;质地纯净、光润、晶莹为好。
Fig. four: Constructing blocks with unique styles and surface area chemistries immediate the formation of distinct crystal symmetries.
结晶�?When sea water is allowed to evaporate, salt crystals are deposited. 海水蒸发后,盐的结晶体就沉淀下来。
水晶内部有多种矿物包裹体,形成的各种景观可以肉眼观测,这样的水晶就是包裹体水晶观赏石。由于水晶本身就是宝石,因此人们称誉包裹体水晶为“宝石级的观赏石”。包裹体水晶观赏石都具有独特性,具有极高欣赏和收藏价值。
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。
Q.four. What's the difference between atomic structure and crystal framework? Ans. The main distinction between atomic read more construction and crystal construction lies within their definitions: atomic composition refers to how atoms are arranged within a one molecule or even a cluster of molecules, Whilst crystal structure considerations the specific arrangement of atoms in just a solid compound.
Solids that have short-vary order but lack extended-array get are referred to as amorphous. Nearly any materials might be produced amorphous by speedy solidification in the soften (molten condition). This affliction is unstable, as well as good will crystallize in time. If the timescale for crystallization is a long time, then the amorphous state appears stable.
15The trick to a great thermoelectric materials is a crystal framework by which electrons can circulation freely.制造一种好的热电材料的关键是,需要一种电子可以自由流动的晶体结构。
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
《古今小说·李公子救蛇获称心》:“器皿皆是玻璃、水晶、琥珀、玛瑙为之,曲尽巧妙,非人间所有。”
