NIOBIUM AND TANTALUM NIOBIUM Niobium is a soft silvery-grey metal that resembles fresh-cut steel. It neither tarnishes nor oxidizes in air at room temperature because of a thin coating of niobium oxide. It does readily oxidize at high temperatures (above 200ºC), particularly with oxygen and halogens. Niobium is not attacked by cold acids but
On-going technological developments, especially in the field of microelectronics and communication have reflected in concomitant increase in the demand for strategic metals such as tantalum (Ta) and niobium (Nb). The extraction of these two metals from ore deposits and secondary resources is based on the generic extractive metallurgical techniques known from …
