Tantalum – Overview of Tantalum Products

Tantalum is one among the rarest elements in the earth’s crust. It is a very hard metal with platinum-gray color and a density of 16.6 g/cm3, a value twice that of steel. The material demonstrates high ductility at high temperatures and superior electrical and thermal conductivity. It has a melting of 2,996 °C, which is the fourth highest of all metals. It has found use in a myriad of applications thanks to its unique combination of physical and chemical properties.

Applications of Tantalum

Tantalum is a material with virtually endless potential. It can form an ultrathin oxide coating that can serve as a protective layer. This quality makes it suitable for producing small, high quality capacitors. With superior resistance to chemicals and high temperatures, tantalum provides several benefits to the chemical process industry in the production of pipelines, heat exchangers and reactor coatings. It exhibits a high degree of biocompatibility, which makes it well suited for use in medical technology as a radiographic contrast agent as well as in the production of implants and bone replacement materials.

In the energy and aerospace industries, the addition of tantalum improves the corrosion resistance of alloys used in turbine blades. A suite of tantalum compounds such as lithium tantalates and tantalum chlorides provides excellent material properties, which are crucial for sophisticated industrial applications. In the fabrication of tool and cutting steels containing carbides, the addition of tantalum and niobium carbide increases their stability and performance. Using tantalum oxides, optical lens manufacturers can achieve thinner lens profiles by optimizing the refractive index of their products.
