Niobium Crucible
Niobium Crucible
A niobium crucible is a container made of niobium metal used for high-temperature applications such as chemical analysis, melting and casting of metals, and crystal growth. Niobium is a refractory metal with a high melting point, excellent corrosion resistance, and good thermal conductivity, making it an ideal material for use in high-temperature applications. Niobium crucibles are commonly used in industries such as aerospace, semiconductor, and metallurgy for their excellent performance under extreme conditions. They can be designed in various shapes and sizes depending on the specific application.

Niobium Crucible Mechanical Property
Niobium is gray, like all other metals. However, by applying a pacifying oxide layer, it will gleam in a beautiful array of colors. In fact, niobium does not just look pretty. Like tantalum, it's resistant to many chemicals and can be formed easily even at low temperatures.
