8Where can we get this magic wand and crystal ball?我们到哪里获得这种魔棒和水晶玻璃球？
the strong condition of numerous straightforward substances, that have a regular condition and surfaces arranged in similar designs
10This is definitely the silicon chip—a bit chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
The purchased inside structure of enormous crystals, just like the fluorite and quartz proven listed here, is mirrored in their geometric shapes.
There's also a lot of materials that resemble crystals but are literally polycrystals. Polycrystals variety when microscopic crystals fuse collectively to sort a strong. These resources tend not to consist of ordered lattices.
⑧、雕刻：立体感强，工艺高，做工精细，成本高。分手工雕刻图形、机器雕刻文字。
Crystals glimpse special from a number of other rocks and minerals, but �?barring some Exclusive situations �?nearly all minerals conceal a crystalline framework beneath the surface.
Ionic Crystals: Electrostatic forces sort ionic bonds. A traditional case in point can be a halite or salt crystal.
Q.four. What is the distinction between atomic framework and crystal composition? Ans. The main distinction between atomic construction and crystal construction lies of their definitions: atomic structure refers to how atoms are arranged inside a single molecule or simply a cluster of molecules, While crystal construction issues the precise arrangement of atoms inside of a solid substance.
广义的包裹体是指宝石内部含有的与主晶宝石化学成分、物理性质等不同的物质。
地质学家目前为止对晶洞形成还没有广泛认同的理论，但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴，甚至动物挖的地洞。经过漫长时间，空腔的外壁变硬，溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间，缓慢渗入的矿物使得晶体在空腔内部结晶。
Orthorhombic: They're rhombic prisms and dipyramids that resemble tetragons but devoid of square cross-sections.
14For instance, Now we have Quartz crystal clocks and watches accurate to inside of one particular minute a calendar year.例如，我们使用的每年误差不超过1分钟的石英水晶钟表和手表。
Binary crystals are located in many constructions. Some pairs of things kind more than one construction. At space temperature, cadmium sulfide may crystallize either during the zinc blende or wurtzite composition. Alumina also has two possible structures more info at area temperature, α-alumina (corundum) and β-alumina. Other binary crystals exhibit different structures at various temperatures. Amongst the most intricate crystals are Those people of silicon dioxide (SiO2), which has seven different constructions at several temperatures and pressures; the most common of these buildings is quartz.
