allotropic การใช้

• The physical properties of carbon vary widely with the allotropic form.
• In 1849 he discovered anhydrous nitric acid ( allotropic forms of silicon and boron.
• Many elements have multiple allotropic forms.
• Sulfur, while usually polycrystalline, may also occur in other allotropic forms with completely different properties.
• The electric motor in the appliance generates ozone ( an allotropic form of oxygen ) that can attack the rubber.
• Typically, elements capable of variable coordination number and / or oxidation states tend to exhibit greater numbers of allotropic forms.
• *If you're in search of more allotropic fun, or other periodic table stuff, is good site.
• The result of this collaboration was the discovery of C 60 and the fullerenes as the third allotropic form of carbon.
• Amorphous silicon is an allotropic variant of silicon, and amorphous means " without shape " to describe its non-crystalline form.
• The allotropic form of silicon range from a single crystalline structure to a completely unordered amorphous structure with several intermediate steps in between.
• So Selenium may have the same allotropic versatility as well ?-- Light current 21 : 57, 31 August 2006 ( UTC)
• A layer of amorphous silicon can be combined with layers of other allotropic forms of silicon to produce a multi-junction solar cell.
• I also added " . . . following phase transitions from one allotropic form to another . " to hopefully make it more clear.
• Thus, irrespective of its allotropic form, carbon remains solid at higher temperatures than the highest melting point metals such as tungsten or rhenium.
• Neodymium commonly exists in two allotropic forms, with a transformation from a double hexagonal to a body-centered cubic structure taking place at about 863 癈.
• Amorphous silicon ( a-Si ) is a non-crystalline, allotropic form of silicon and the most well-developed thin film technology to-date.
• Anton Schr鰐ter von Kristelli discovered in 1850 that heating white phosphorus at 250 癈 in an inert atmosphere produced a red allotropic form, which did not fume in contact with air.
• At atmospheric pressure, there are three allotropic forms of iron : ferrite, gamma iron ( ? ) a . k . a . austenite, and delta iron ( ? ).
• Monocrystalline silicon differs from other allotropic forms, such as the non-crystalline amorphous silicon used in thin-film solar cells and polycrystalline silicon, that consists of small crystals, also known as crystallites.
• On extending this inquiry to other allotropic crystals, he observed a similar variation, and was thus led, in 1825, to the discovery that allotropic crystals, when heated, expand unequally in the direction of dissimilar axes.
