Processing of columbite-tantalite ores and concentrates for niobium and niobium compounds in electronic applications

International Symposium Niobium 2001

A small percentage of Niobium and Niobium compounds produced in the world is being used in sofisticated electronic components and systems, such as capacitors, piezoelectric devices and optical circuits. This paper briefly describes the outline of the production process of these materials and their main characteristics. (AU)
