the reliable state of many uncomplicated substances, which have a regular form and surfaces organized in similar designs
10This could be the silicon chip—slightly chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
If you wish to see how crystals are formed, you'll be able to do a little undertaking in your pretty personal kitchen area and see the formation in the crystals come about using your own eyes . This can be completed by Placing a little volume of table salt into some common tap water, wait 24 hrs, and you will see great cubed formations. This happens since the water is evaporating, which results in the atoms which make up the salt (the mineral) plus the water to return nearer with each other.
水胆水晶，包括气态，液态，固态，有时候可以同时多态并存，无色居多，个别情况下可见红色，绿色，黄色，蓝色，黑色等。
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�?。

隐晶类水晶外观是一块块的，不是成六角水晶簇状，但他们却也是属六方晶系的。但我们不能以肉眼观察到他们的六角形结晶，因为结晶的体积极为细小，需以显微镜协助下才能看到六角开结晶。而此类水晶非常平滑，因为结晶之间有“水化硅石”填补，玛瑙便属于此类。
Crystals are more info categorised generally classes, including insulators, metals, semiconductors, and molecular solids. An individual crystal of an insulator is frequently clear and resembles a piece of glass. Metals are shiny unless they have got rusted. Semiconductors are sometimes shiny and occasionally transparent but are in no way rusty. Numerous crystals may be classified as one type of solid, while others have intermediate conduct. Cadmium sulfide (CdS) can be well prepared in pure form and is an excellent insulator; when impurities are extra to cadmium sulfide, it will become an interesting semiconductor.
