Scandium is an element with the atomic number 21 and represented by the symbol ‘ Sc ‘ in the periodic table. Scandium is mined from one of the rare minerals from Scandinavia. The colour it develops when exposed to air is yellowish or pinkish cast. One of the characteristics of Scandium is it gets tarnished and burned easily if ignited.احصل على السعر

The demand is about 50% higher, and both the production and demand keep increasing.احصل على السعر
A rare transition element, scandium was discovered in 1878 by L. Nilson in Scandinavia. It occurs in only trace amounts on earth, though it is much more abundant in the sun and other stars. Although scandium can develop a slightly yellow or pink tinge upon exposure to air, it exists in its standard state as a soft, silvery white metal. Scandium’s high melting point احصل على السعر

A relatively soft element, scandium resembles yttrium and the rare-earth metals more than it resembles aluminum or titanium. It is a very light metal and has a much higher melting point than aluminum, making it of interest to designers of spacecraft.
