What is special about niobium?
A silvery metal that is very resistant to corrosion due to a layer of oxide on its surface. Niobium is used in alloys including stainless steel. It improves the strength of the alloys, particularly at low temperatures.
Is niobium very reactive?
Apart from reacting with oxygen in air at high temperatures, niobium is reactive to carbon, nitrogen, sulfur and halogens. Niobium is non-reactive to acids and moisture at room temperatures but reacts with acids at elevated temperatures. Niobium and its compounds may cause irritation to eyes and skin.

What is the texture of niobium?
Niobium is a shiny, white, ductile metal. In air an oxide layer forms whose color depends on its thickness. Shades of blue, green and yellow are typical.
What is the state of matter for niobium?
solid
Classified as a transition metal, Niobium is a solid at room temperature.
Is niobium a solid liquid or gas?
Niobium is a chemical element with symbol Nb and atomic number 41. Classified as a transition metal, Niobium is a solid at room temperature.
What type of metal is niobium?
transition metal
Niobium, also known as columbium, is a chemical element with the symbol Nb (formerly Cb) and atomic number 41. Niobium is a light grey, crystalline, and ductile transition metal. Pure niobium has a Mohs hardness rating similar to that of pure titanium, and it has similar ductility to iron.
Is niobium hard or soft?
Niobium is a chemical element (symbol Nb). It is a soft, grey metal that is naturally found in the minerals pyrochlore and columbite.
