A solid is crystalline if it has prolonged-range buy. As soon as the positions of the atom and its neighbours are known at one particular stage, the put of each atom is known exactly throughout the crystal. Most liquids lack extended-array order, While many have quick-selection buy. Brief assortment is defined as the primary- or 2nd-nearest neighbours of the atom. In many liquids the 1st-neighbour atoms are organized in precisely the same construction as in the corresponding strong stage.

Chemical Bonds The categories of chemical bonds fashioned between atoms or groups of atoms in crystals rely upon their dimension and electronegativity. You will find four classes of crystals as grouped by their bonding:
养殖晶：养殖晶是指，用天然水晶做种子，然后赋予天然水晶生长的高压条件，养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长，这样的水晶成分（分子式）与天然水晶是一摸一样的，唯一有差别的是，这样的水晶磁场作用没有天然水晶强。
Crystalline framework is characterised by a geometrical, repeating sample of symmetric molecular structure. The arrangement of atoms varieties these ordered, repeating patterns.
Monoclinic �?Characterised by three unequal axes, two of which intersect at an oblique angle, whilst the third is perpendicular to the airplane of one other two.
⑦、镀彩：运用类似电镀的手法在水晶表面以不同的色彩，层面较薄，经摩擦可划伤�?；出现划痕，由于镀彩经常位于底部，因此在镀彩底部经常采用其它对象附着，如生肖文镇。
11I carefully opened the offer and located a crystal bell inside.我小心地打开包裹，发现里面有一个水晶钟。
水晶常以晶簇、晶洞形式产出，其中水晶洞一般存在于由火山喷发而形成的巨厚熔岩流层的火成岩与玄武岩中。火山喷发时所含的气体或热水溶蚀等作用导致岩层中出现大量的孔隙，当富含硅质矿物的流体进入较薄的熔岩孔隙中，且温、压条件合适时将结晶沉淀出水晶等矿物。
多色�?无色水晶没有多色性。有色水晶有弱到强的多色�?表现为体色的不同深浅。
Single crystals of metals are gentle and malleable, when polycrystalline metals are harder and much better and tend to be more handy industrially. Most polycrystalline products may be produced into huge single crystals soon after extended heat therapy. In the past blacksmiths would warmth a piece of metal to make it malleable: warmth will make some grains expand substantial by incorporating scaled-down ones. The smiths would bend the softened metallic into read more form and then pound it awhile; the pounding would help it become polycrystalline again, increasing its power.
Crystallography would be the examine of crystals, and it offers with anything from excellent geometric styles to seemingly random conglomerations of particles and minerals.
Crystals are categorized generally types, for instance insulators, metals, semiconductors, and molecular solids. Just one crystal of the insulator is normally transparent and resembles a piece of glass. Metals are shiny Except they have got rusted. Semiconductors are occasionally shiny and sometimes clear but are never rusty. A lot of crystals is usually categorised as only one type of strong, while others have intermediate conduct. Cadmium sulfide (CdS) is usually ready in pure type and is a wonderful insulator; when impurities are added to cadmium sulfide, it becomes an interesting semiconductor.
水晶观赏石在形态、质地、内部特征等方面往往十分奇异。大自然有无限风光，都可以在包裹体水晶种找到缩影。
