Mô tả

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).
