Calcite crystals are frequently Utilized in optical machines, and even the graphite in pencil lead are sheets of crystals that effectively break apart layer by layer to jot down. Silica can kind silicate crystals that are the basis for quartz, mica, olivine, and a number of other crystals and minerals.
12He tried once more in various other towns and succeeded with Crystal Caramels.他又在其他几个城市再次尝试，并成功制出了水晶焦糖。
Chemical Bonds The types of chemical bonds fashioned concerning atoms or groups of atoms in crystals depend on their measurement and electronegativity. You will find four classes of crystals as grouped by their bonding:
We've penned about around three hundred stones in the mineral kingdom! Read about Every stone's unique origin, record, and energies down below.
There's also several products that resemble crystals but are literally polycrystals. Polycrystals variety when microscopic crystals fuse collectively to sort a solid. These resources never encompass ordered lattices.
They will inevitably come up with a great little uniform cluster of atoms, That is the process of increasing crystals. The greater they can occur jointly, the greater of the formation is going to be obvious to the bare eye. Experts can ascertain what mineral They're thinking about by how the crystals form.
时尚的收藏爱好者喜欢收藏天然水晶，却常常因为在市场上面对大量的合成水晶看走了眼。市面上的水晶：
Crystals might be developed below reasonable disorders from all 92 The natural way developing elements except helium, and helium might be crystallized at small temperatures by making use of 25 atmospheres of strain.
仿制钛晶树水晶：钛晶是水晶里价格最昂贵的，造假者当然也不会放过这么好的产品。天然的环境下，在水晶里能生长个像树一样的钛晶，完全是可能的，只是这样的货很少，那我们的造假专家是如何做的呢，白水晶底下打个洞，激光打点成板状的钛晶进去，就这样这块水晶的身价就能飙升几十倍。往往有的钛晶戒面，会采用将钛晶部位割成板状，与圆面的水晶粘合的方法来制作。

正常的水晶在生长时，多可以发现和柱形尖端棱线平行的生长纹（expansion lines）。由于在地底、岩洞中的生长空间多狭窄，尤其在遇到地震时，或地壳变动时，甚至容易遭到其他矿石的挤压，常常会压迫产生不同的「晶面」。还有，当水晶还是在液态状的时候，常常也会包覆着其他的矿石、泥灰一起结晶成长，如金红石（稍后变成发晶）、火山泥灰（稍后变成幻影水晶）等等。所有的这些，都是「自然的一部分」，请不要视为「瑕疵」。
crystal, any good material wherein the component atoms are arranged in the definite pattern and whose floor regularity displays its interior symmetry.
Yet another sort of crystalline carbon is based on the molecule with 60 carbon atoms referred to as buckminsterfullerene (C60). The molecular form is spherical. Each carbon is bonded to a few neighbours, as in graphite, as well as the spherical form is obtained by a mix of twelve rings with 5 sides and twenty rings with six sides. Comparable constructions were being first visualized through the American architect R. Buckminster Fuller for geodesic domes.
