Yttrium

CAS number : 7440-65-5

Molecular weight :88.91

Molecular formula/chemical symbol :Y

Description :
 

Yttrium is a silver with metallic luster of rare earth metals, and it is very stable in the air, the chemical characteristics of lanthanum and its similar. Yttrium debris in the air in 400 degrees Celsius above can be spontaneous combustion, its powder in the air is very unstable. In the nuclear absorption process it in cross section is very small. General yttrium oxide price for + 3 price.Atomic weight: 88.91. Silver metal. Density: 4.469 g/cm3 (twenty ℃). Melting point: 1438 ℃. Boiling point: 338 ℃. Electronegativity: 1.22 (BaoLinBiao degree). Heat resistance: 300 J/kg k.). Conductivity: 1.66 x 106 / (m ohm). Thermal conductivity: 17.2 W/(m. K).

USES :

The main use of special steel and non-ferrous metal additive, making superconductor and super alloy, electronic and atomic energy industry functional material (as yttrium phosphor screen to produce red color, also used in X-ray filter).
