Chemical Bonds The categories of chemical bonds formed involving atoms or groups of atoms in crystals rely on their sizing and electronegativity. There are actually 4 categories of crystals as grouped by their bonding:
③次生包裹体：指主体水晶形成后，由于环境的变化使得主晶周围的一些物质沿裂隙进入到其内部而形成的包裹体。形成的原因有出熔作用、裂隙的结晶化、以及放射性元素破坏的作用等。水晶典型的次生包裹体有胶花水晶中的氧化铁充填物等。
There are also several supplies that resemble crystals but are literally polycrystals. Polycrystals kind when microscopic crystals fuse with each other to sort a sound. These elements will not encompass ordered lattices.
They will inevitably generate a nice small uniform cluster of atoms, this is the whole process of growing crystals. The more they might appear with each other, the more of a formation will likely be seen to the naked eye. Researchers can identify what mineral They're checking out by how the crystals variety.
水晶内部有多种矿物包裹体，形成的各种景观可以肉眼观测，这样的水晶就是包裹体水晶观赏石。由于水晶本身就是宝石，因此人们称誉包裹体水晶为“宝石级的观赏石”。包裹体水晶观赏石都具有独特性，具有极高欣赏和收藏价值。
如果水晶内部杂质中有传说中人物的造型，如佛、星座、生肖等价值可能要高于同等颜色和净度的水晶。
包裹体常见有固相、固液气三相组合、空洞以及双晶、色带等。水晶中典型的同生包裹体有自形的锐钛矿、气液两相包体等。
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。
Through the Cambridge English Corpus We are saying the chain topology within the higher w location acts since the proverbial ' scratch-on-theglass ' necessary inside the organic and natural chemistry laboratory for making crystals. In the Cambridge English Corpus Continual-tension and temperature molecular-dynamics simulations of crystals of your lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. From your Cambridge English Corpus Besides these, dust particles happen to be observed in small-temperature plasmas, like All those Employed in plasma processing and plasma crystals. Through the Cambridge English Corpus The final A part of the e book concentrates on peculiarities of strongly coupled dusty plasmas, like the formation of dust crystals and related beautiful forces. From the Cambridge more info English Corpus Comprehensive characterization of damage threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. Through the Cambridge English Corpus Unbroken crystals are euhedral; rounded, or maybe more irregular, Most important morphologies were not noticed. Within the Cambridge English Corpus See all samples of crystal These examples are from corpora and from resources on the internet. Any thoughts in the illustrations will not symbolize the impression on the Cambridge Dictionary editors or of Cambridge University Push or its licensors.
Crystal Lattices You can find seven units of crystal buildings, which happen to be also called lattices or Room lattices:
玉石纹理如果能形成美丽的花纹、图案，其价格就高，如玛瑙内红白相间的色带有规律地排列，形成缠丝玛瑙时，碧玉中的不均匀颜色形成一种风景图案时，材料的价值将提高。当水晶内包裹体形成美丽的图案时，如幽灵水晶、风景水晶，或者针状包裹体呈束状排列时，其价值都高于普通的水晶。图案越美观、越有意境越好。
This crystal composition is to blame for the exceptional physical and chemical properties of sodium chloride, together with its significant melting point, electrical conductivity, and skill to sort ionic bonds very easily.
