NIOBIUM AND TANTALUM
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

Tantalum and Niobium: Similarities and Differences
For instance, tantalum is much denser than niobium, with a density of 16.65 g/cm3 compared to 8.57 g/cm3 for niobium. Tantalum also has a higher melting point (2996 °C) and boiling point (5425 °C) than niobium (2477 °C and 4744 °C respectively). Tantalum is slightly harder than niobium, with a Mohs hardness of 6.5 versus 6 for niobium.
