Utilization
Its emissivity as well as its ability to adsorb gases and its refractoriness determine its use for the production of parts of electric-vacuum devices. Tantalum sheet is widely used in the manufacture of cathodes. It is also used:
- In the chemical industry in the manufacture of laboratory utensils.
- Parts of heat-exchange equipment.
- In the pulp and paper industry and processing sector, the products are used to make corrosion-resistant parts.
- In surgery, tantalum thread is used to bind ligaments, nerve tissue due to its biological inertness.
