An obsolete group name for minerals with the general formula (Mn,Fe)(Ta,Nb) 2 O 6, equivalent to the Tantalite-(Fe)-Tantalite-(Mn) Series.Generally mangan-dominant members are more abundant in nature. Many specimens called tantalite actually belong to the columbite series or tapiolite series. Visit gemdat for gemological information about Tantalite.

Niobium and columbium are synonymous names for the chemical element with atomic number 41; columbium was the name given in 1801, and niobium (Nb) was the name officially designated by the International Union of Pure and Applied Chemistry in 1950. Niobium in the form of ferroniobium is used worldwide, mostly as an alloying element in steels and in superalloys.

Tantalum alloys are used in a variety of high-stress applications, such as nuclear reactors, cutting tools, missiles, aircraft and chemical processing equipment.
