Characteristics of niobium crucible

 ✅ High melting point: 2468 ° C, suitable for high-temperature melting (such as oxides, rare earth metals, etc.).

 ✅ Corrosion resistance: resistant to acid, alkali, and molten metal corrosion (such as Li, Na, K, etc.).

 ✅ Low heat neutron absorption cross section: suitable for molten salt reactors (MSR) in the nuclear industry.

 ✅ High thermal conductivity: High thermal conductivity efficiency and uniform temperature distribution.

 ✅ Superconducting properties: Can be used for research on low-temperature superconducting materials, such as the preparation of Nb ∝ Sn superconductors.
