99.95% чиста ниобиева плоча разпръскваща цел

Niobium is a lustrous, grey, ductile, paramagnetic metal in group 5 of the periodic table, with the outermost shell having a different electron configuration than group 5. Metals take on a bluish tinge when exposed to air for long periods of time at room temperature. Despite its high melting point (2,468 °C) in its elemental form, it is less dense than other refractory metals. Additionally, it is corrosion resistant, has superconducting properties, and forms a dielectric oxide layer.
