Calcite crystals tend to be used in optical products, as well as the graphite in pencil lead are sheets of crystals that primarily crack apart layer by layer to write down. Silica can sort silicate crystals which happen to be the basis for quartz, mica, olivine, and all kinds of other crystals and minerals.

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 is definitely the silicon chip—somewhat 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。

C2 [ U ] transparent glass of quite high quality, normally with its surface area Slice into delicate styles:

Monoclinic �?Characterized by 3 unequal axes, two of which intersect at an oblique angle, when the third is perpendicular to the aircraft of another two.

解理：无解理。所谓解理是指矿物被打击时，沿一定方向有规则地裂开形成光滑平面的性质。根据解理的程度可以分为五类：极完全解理、完全解理、中等解理、不完全解理和无解理，水晶属于无解理。

Being a hot solution cools or simply a saturated Answer evaporates, particles draw close plenty of for chemical bonds to sort. Crystals may form from deposition straight from the fuel stage. Liquid crystals have particles oriented within an structured way, like good crystals, however can flow.

Amongst the binary crystals, the simplest constructions to visualize are Individuals with equal numbers of The 2 sorts of atoms. The construction of sodium chloride relies over a dice. To construct the lattice, the sodium and chlorine atoms are put on alternate corners of a dice, along with the composition is recurring (Figure 3B).

颜色：无色，浅至深的紫色，浅黄、中至深黄色，浅至深褐、棕色，绿至黄绿色，浅至中粉红。

Solitary crystals of metals are smooth and malleable, even though polycrystalline metals are more challenging and more robust and tend to be more useful industrially. Most polycrystalline products is often designed into significant one crystals after prolonged warmth therapy. Before blacksmiths would warmth a bit of metallic to really make it malleable: heat would make a number of grains develop big by incorporating smaller types. The smiths would bend the softened metal into condition after which you can click here pound it awhile; the pounding would make it polycrystalline all over again, increasing its power.

Molecular Crystals: Overall molecules are bonded to each other in an organized method. A very good instance is usually a sugar crystal, which has sucrose molecules.

⑤、打孔：是在水晶成品未完成前，根据其所需打孔之尺寸及位置，以钻头加工，如制表件、笔筒、瓶孔等。

水晶的价值根据品质、块体的大小、美感和产量多少的不同相差较大。遇到好的天然水晶要敢于下手，但好的水晶一般大家都想得到，值与不值，就要看经验了。由于天然水晶的开采和制作原因，没有瑕疵的水晶很难得到，纯净的饰品要达到与合成水晶媲美的品质，实在是很难得。另外，由于水晶的特性，在佩戴过程中，也会改变其等级，比如因为某种原因，有可能会逐渐产生较大裂纹。
