• Tantalum | Plansee

    Tantalum occurs most frequently naturally in the form of tantalite ore which has the formula (Fe,Mn) [(Nb,Ta)O 3] 2. When the tantalum content predominates, the ore is referred to as tantalite. When more niobium than tantalum is present, it is known as columbite or niobite.

  • Products Tantalum

    The tantalum supply chain can be relatively lengthy in terms of raw material traceability. Originating from the mining of ore to the manufacturer of the finished product, whether electrical equipment or turbine blades, the supply chain can include intermediaries such as traders and distributors and be sourced from multiple suppliers at any step in the process.

    Tantalum is a bee transition metal with a melting point of 3000°C. Its investigation is of interest mainly for two reasons. First Ta is suitable for the examination of basic aspects of deformation, recovery, and recrystallisation of ~ bee metals over a wide temperature range, since it does not undergo phase transformation during annealing. . Secondly Ta is of industrial importance due to its ...

    Tantalum is produced by the processing and refining of its ore tantalite. Tantalite is the mineral ore containing tantalum. Most tantalum mines are open pit whereas some are underground. The mining process involves blasting, crushing and transporting the tantalite ore to start the process of separating tantalum.
