scandium yttrium magnesium

Scandium (Sc) Iron (Fe) Yttrium (Y) Palladium (Pd) Palladium is a shiny, silvery-white metal that melts at 1555 C and has a density of 12.02g/cm 3. The metal is highly corrosion resistant in air but may tarnish in moist air containing sulphur. It has no biological 2017/6/8Scandium has small ions, which permits it to develop chemical reactions with elements such as magnesium and zirconium. Although it is non-toxic to humans in its elemental form, precautions must be taken when scandium is present in the environment because of the chance of breathing in its gases .

Yttrium — Wikipdia

L'yttrium est l'lment chimique de numro atomique 39, de symbole Y. L'yttrium est un lment de transition d'apparence mtallique, qui possde un comportement chimique proche de celui des lanthanides, et class historiquement parmi les terres rares, avec le scandium et les lanthanides [7]..

Magnesium is a chemical element with the symbol Mg and atomic number 12.It is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column (group 2, or alkaline earth metals) of the periodic table: all group 2 elements have the same electron configuration in the outer electron shell and a similar crystal structure.

Magnesium was present in the water of a certain farmer in Epsom, England, where it was found to heal rashes and other skin problem – thus the name Epsom salts. Magnesium is an abundant element, and is essential to the cells of all known living organisms.

group-3 Sc-relative yttrium (e.g. AlYN) could provide materials with ferroelectric behavior. Moving from group 3, the quaternary alloy aluminium magnesium niobium nitride (AlMgNbN) is another contender, they report. Magnesium is group 2 and niobium is group 5.

2016/5/16It is now clear that alloys with a small "atomic" percentage of scandium in aluminum and magnesium matrices show remarkable resistance to oxidation and exhibit unexpected strength. Therefore, if there were scandium available at a good price then the aircraft, marine, and land transportation industries would buy and use such alloys.


Sc Scandium Element Information: Facts, Properties,

Scandium is a chemical element with symbol Sc and atomic number 21. A silvery-white metallic d-block element, it has historically been sometimes classified as a rare earth element, together with yttrium and the lanthanoids. It was discovered in 1879 by spectral

Le scandium appartient la famille des terres rares (lanthanides + scandium + Yttrium). Les terres rares ont tous des proprits comparables. Les terres rares sont essentiellement prsents dans deux types de minerais: la monazite et la bastnasite.
