More info

Niobium (Nb) is the lightest refractory metal characterized by its high melting point, excellent high-temperature strength, specific strength, and non-radioactive nature. These properties make it a favored material for thermal protection and structural components in aerospace engines. Niobium powder is primarily produced through high-temperature reduction of niobium, ensuring high purity during synthesis.
