NIOBIUM AND TANTALUM PROMETIA

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
