Tantalum and niobium are...tanb.png

  • refractory metals with melting points of 3,017°C and 2,477°C
  • excellent materials for capacitor anodes as they form an extremely thin but dense oxide layer as dielectric 
  • highly corrosion resistant and ductile at elevated temperatures
  • biocompatible and not allergenic materials, best suited to medical applications
  • ideal diffusion barriers (e.g. for semiconductor industry)
  • soluble in one strong acid

Excellent energy density in high performance tantalum capacitors

Tantalum capacitors have a high energy density and due to their stable temperature and BIAS characteristics, they are superior to other materials.  Their reliability has been proven for decades and therefore they are truly the technology of choice for mobile devices, medical devices, automotive and defense applications.

Leading edge semiconductors

High-speed data processing in leading-edge semiconductors is made possible by using copper in semiconductors. To prevent copper from diffusing into the semiconducting layers, Ta or TaN is used as thin but effective barrier layer. Key applications include logic Integrated circuits (IC) and memory chips (DRAM, NAND-Flash).

High reliability under extreme conditions

Tantalum and niobium are characterized by high corrosion resistance and ductility at elevated temperatures. These properties provide many benefits to the chemical process industry, for instance, in the production of reactor coatings, heat exchangers and pipelines. In the aerospace and energy industries, tantalum and niobium increase the corrosion resistance of alloys in turbine blades.
Based on lithium tantalate, lithium niobate surface acoustic wave filters enable mobile communication in the required complexity and frequency. Therefore, they are applied in every device using mobile communication standards in relation to the Internet of Things (IoT).
Last but not the least, niobium is the element with the highest transition temperature and therefore highly suitable for superconductor applications. Pure niobium and niobium alloys are used in Magnetic Resonance Imaging (MRI), NMR Collider or fusion reactors.
