These crystals ended up shaped in excess of a million yrs back Within the Earth's crust. They take place in the event the liquid inside the Earth consolidates plus the temperature chills. Other crystals sort when the liquid can make its way throughout the clefts and dispense minerals in to the clefts.
Bismuth (Bi) seems to generally be a metallic, but the amount of electrons available for electrical conduction is comparable to that of semiconductors. In reality, bismuth is known as a semimetal. Molecular solids are usually crystals shaped from molecules or polymers. They are often insulating, semiconducting, or metallic, according to the kind of molecules in the crystal. New molecules are continuously getting synthesized, and lots of are created into crystals. The amount of distinct crystals is gigantic.
水晶文化历史悠久，古人曾赋予它一串极富美感的雅称：水玉、水精、水碧、石英等。
Incorporate to word listing Add to word record C2 [ U ] transparent glass of quite premium quality, usually with its surface area Slash into sensitive patterns
条痕颜色：无色。矿物粉末的颜色叫条痕。它可以消除假色，减弱他色，保留自色，是比矿物的颜色更为可靠的鉴定特征之一。
你们都知道，拿起一个水晶棱镜，让一束阳光通过它，就会得到一个光谱，看起来就像一条连续的彩虹色带。
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。

第三种是“皮景”，因某些其他的矿物与水晶体共生，或由于其他的物质侵蚀而依附于水晶表面，或者是水晶受自然环境的影响，在水晶表面出现蚀象，形成了一些景象或图案，这种景观存在于水晶表面。
晶体 Silicon crystals grown in a very laboratory convert light-weight into electrical Power. 在实验室中长成的硅晶体可将光线转变为电能。
With the Cambridge English Corpus We are saying the chain topology while in the substantial w location acts because the proverbial ' scratch-on-theglass ' wanted inside the organic and natural chemistry laboratory to help make crystals. From the Cambridge English Corpus Frequent-force and temperature molecular-dynamics simulations of crystals with the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. From your Cambridge English Corpus Together with these, dust particles have already been noticed in very low-temperature plasmas, like Those people Utilized in plasma click here processing and plasma crystals. Through the Cambridge English Corpus The final Element of the ebook concentrates on peculiarities of strongly coupled dusty plasmas, like the formation of dust crystals and linked appealing forces. Within the Cambridge English Corpus Full characterization of injury threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. In the Cambridge English Corpus Unbroken crystals are euhedral; rounded, or even more irregular, Principal morphologies weren't noticed. From the Cambridge English Corpus See all examples of crystal These examples are from corpora and from sources on the internet. Any viewpoints during the examples usually do not stand for the viewpoint of your Cambridge Dictionary editors or of Cambridge University Press or its licensors.
You will find only a few distinctive device-cell designs, so a number of crystals share an individual device-cell form. A crucial attribute of the device cell is the volume of atoms it includes. The overall range of atoms in the entire crystal will be the selection in each cell multiplied by the amount of unit cells. Copper and aluminum (Al) Every single have a person atom per unit cell, when zinc (Zn) and sodium chloride have two. Most crystals have only some atoms for each device cell, but there are numerous exceptions. Crystals of polymers, by way of example, have 1000s of atoms in Every unit mobile.
crystal, any good substance in which the ingredient atoms are organized in the definite sample and whose floor regularity displays its internal symmetry.
Tetragonal �?Characterised by three mutually perpendicular axes, two of which might be equal in length, even though the third is longer or shorter and perpendicular to another two.
