Niobium and tantalum are transition metals that are almost always found together in nature because they have very similar physical and chemical properties. Their properties of hardness, conductivity, and resistance to corrosion largely determine their primary uses today.

About the Tantalum-Niobium International Study Center (T.I.C.) An international, non-profit association founded in 1974 under Belgian law.

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.

The purpose of the association would be to spread information about tantalum and to promote the common interest and welfare of the producers, especially with public and private authorities, organisations and agencies. They gathered together several representatives of producers to work out the principles and charter of such an organisation.
