Characteristic:
1. High melting point: The melting point of niobium is approximately 2468°C, making it excellent in high temperature applications.
2. Corrosion resistance: Niobium has good corrosion resistance to most acids and alkalis and maintains this property even at high temperatures.
3. Superconductivity: Pure niobium has superconducting properties at low temperatures, that is, it can conduct current without resistance below the critical temperature.
4. Good mechanical properties: Niobium can maintain good strength and hardness even at high temperatures.
5. Biocompatibility: Niobium has good compatibility with human tissues and is suitable for medical device manufacturing.
Application:
1. Electronics industry: used as substrate or diffusion barrier layer for electronic components, and as capacitor materials in the production of very large scale integrated circuits (VLSI).
2. Superconducting magnets: Superconducting magnets used in particle accelerators and magnetic resonance imaging (MRI) equipment.
3. Chemical engineering: As a material for chemical reactors and pipelines, utilizing its high temperature resistance and corrosion resistance properties.
4. Aerospace: Used in certain components of spacecraft and rockets, especially those that require high temperature resistance.
5. Medical devices: used to manufacture implantable medical devices, such as pacemakers and artificial bones.
6. High temperature furnaces and heating elements: Due to its high melting point, it can be used as an integral part of industrial furnaces or heating equipment.
7. Decoration and Crafts: Due to its appearance and durability, niobium can also be used in high-end decorations and crafts.
Due to niobium's high reactivity and processing difficulty, the production and processing of niobium plates often require special technology and equipment. Additionally, niobium plates and their products are generally more expensive due to niobium's rarity and refining costs. As technology advances, the application of niobium plates may further expand, especially in high-tech fields that require extreme environmental stability.
