Calcite crystals are often Utilized in optical devices, and also the graphite in pencil lead are sheets of crystals that primarily crack aside layer by layer to jot down. Silica can kind silicate crystals which are the basis for quartz, mica, olivine, and a number of other crystals and minerals.
23Sometimes, however, the crystal form of the silicate inclusions is noticed to resemble more carefully The interior framework 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。
4Without a crystal ball, It is not possible to mention in which we are going to be future calendar year.不用水晶球预卜未来，我们说不准明年处境如何呀。《牛津词典》
Most reliable components found in character exist in polycrystalline kind rather than as a single crystal. They are actually composed of millions of grains (little crystals) packed alongside one another to fill all space. Just about every particular person grain has another orientation than its neighbours. Though very long-variety buy exists in just 1 grain, with the boundary between grains, the purchasing improvements direction. A typical bit of iron or copper (Cu) is polycrystalline.
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。
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�?。
水晶原石观赏石，从字面意义理解：观赏水晶石的原貌，即经过抛光去皮后的包裹体水晶和原色水晶，不需雕刻不求象形就具有非常高的观赏价值和收藏价值。此类水晶观赏石对质地要求非常之高，水晶晶体通透干净，颜色艳丽，意境鲜明深刻的价值就高，它的价值特点就好比钻石，实实在在石头本身的价值。
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。
Crystals are sometimes seen as one thing of enormous splendor, and they are commonly employed with diamonds or other stones to create parts of jewelry. The majority of crystals now are gentleman-designed in laboratories.

15The trick to a very good thermoelectric content is really a crystal framework wherein electrons can movement 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。
Crystals are not simply renowned for their Bodily visual appearance, but various crystals of different elements and formations may lead to a vast read more selection of utilizes and Actual physical Attributes.
Crystals are classified normally types, for instance insulators, metals, semiconductors, and molecular solids. An individual crystal of the insulator will likely be transparent and resembles a bit of glass. Metals are shiny unless they have got rusted. Semiconductors are occasionally shiny and occasionally transparent but are in no way rusty. A lot of crystals is often classified as an individual kind of reliable, while others have intermediate conduct. Cadmium sulfide (CdS) is often well prepared in pure form and is a superb insulator; when impurities are additional to cadmium sulfide, it results in being a fascinating semiconductor.
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。
