Niobium (Nb) Pellets Evaporation Materials
Niobium is classified as a transition metal on the Periodic Table of Elements. It is often found in nature with tantalum; hence it mimics many of its properties. It has a melting point of 2,468°C, a density of 8.57 g/cc, and a vapor pressure of 10-4 Torr at 2,287°C. While typically metallic gray in color, it is known to take on a bluish tinge when exposed to air. It is used in various superconducting alloys and is a common element in jewelry production. Niobium and its compounds and alloys are evaporated under vacuum to make semiconductor, optical and wear resistant coatings.
