Niobium Crucible, or Niobium Cup, finds extensive use in high-temperature engineering applications (exceeding 1200°C). The Niobium Crucible serves various purposes, acting as a container in rare-earth metallurgy and load plates for tantalum and niobium electrolytic capacitors with high-temperature sintering. Additionally, it finds application as a corrosion-resistant container in chemical industries and evaporation crucibles and liners.
