杂质、裂纹越少越好。质地好的水晶制品,应看不到星点状、云雾状和絮状分布的气液包裹体或组成玉石的颗粒。有裂纹、斑点,则属于次品。

10This will be the silicon chip—a little chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。

第一种是“全包裹体”,在水晶结晶的时候把这些物质包裹在晶体里面,这类包裹体所形成的各种景象,大多保持了水晶结晶时的原状,也就是说保存了几亿年的原状,极少受到自然环境的影响。

根据美国已经了解的情况,统计局的专家和其他人口统计学家在他们的视野中提供了一个不可抗拒的水晶球。

当二氧化硅结晶完美时就是水晶;结晶不完美的就是石英:二氧化硅胶化脱水后就是玛瑙;二氧化硅含水的胶体凝固后就成为蛋白石;二氧化硅晶粒小于几微米时,就组成玉髓、燧石、次生石英岩。

石英:《广雅》称水晶叫石英,色白如莹者又叫白。为附的异形字。司马相如《子虚赋》就�?�?雌黄�?�?之句。苏林解释:�?�?,白石英�?”。

Crystals may be grown underneath average ailments from all ninety two In a natural way taking place components besides helium, and helium may be crystallized at lower temperatures by making use of twenty five atmospheres of strain.

包裹体常见有固相、固液气三相组合、空洞以及双晶、色带等。水晶中典型的同生包裹体有自形的锐钛矿、气液两相包体等。

[ C/U ] transparent glass of top of the range, typically with its floor Slash into patterns that replicate mild

被主体水晶所捕获的包裹体。原生包裹体通常为固相,形态较规则。水晶中典型的原成包裹体有金红石、电气石、黄铁矿等,也会见到岩石碎屑或集合体。

The sodium chloride crystal lattice is characterized from the close packing of your beneficial sodium ions and negative chloride ions. Each sodium ion is surrounded by 6 chloride ions, and every chloride ion is surrounded by six sodium ions, developing a hugely stable and symmetrical composition.

水精:水晶为何称为水精,《广雅》有巧解:�?水之精灵�?”;李时珍则说:�?莹洁晶光,如水之精英 ”。细加考究,此称还蕴含浓厚的宗教意味呢。水精一名,最初见于佛书,后汉支曜翻译的《具光明定意经》说:�?其所行道,色如水�?�?。

Binary crystals are present in numerous constructions. Some pairs of components form click here more than one structure. At space temperature, cadmium sulfide may crystallize possibly in the zinc blende or wurtzite framework. Alumina also has two attainable constructions at room temperature, α-alumina (corundum) and β-alumina. Other binary crystals exhibit distinctive buildings at unique temperatures. One of the most intricate crystals are All those of silicon dioxide (SiO2), which has 7 diverse buildings at different temperatures and pressures; the commonest of these buildings is quartz.
