What is niobium classification?
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 makes niobium unique?
Niobium is abbreviated Nb, and is element number 41 on the periodic table. It has an atomic weight of 92.90638 and a specific gravity of 8.57. Niobium has a melting point of 2750 K (2477°C or 4491°F), and a boiling point of 5017 K (4744°C or 8571°F). Niobium can have a valence of +2, +3, +4, or +5.
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 kind of metal is niobium?
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.
How strong is niobium?
Density (near r.t. ) 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.
What is an interesting fact about ruthenium?
Interesting Ruthenium Facts Ruthenium was the last of the platinum group metals to be discovered. The element name comes from the Latin word ‘Ruthenia’. Ruthenia means Russia, which refers to the Ural Mountains of Russia, the original source of the platinum metal group ores.
Is niobium very reactive?
The physical and chemical properties of niobium are similar to tantalum. 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.
What are 3 uses for ruthenium?
Ruthenium oxide is used in the chemical industry to coat the anodes of electrochemical cells for chlorine production. Ruthenium is also used in catalysts for ammonia and acetic acid production. Ruthenium compounds can be used in solar cells, which turn light energy into electrical energy.
Can ruthenium burn forever?
It has been discovered that ruthenium is behind the never-ending fires in Southern Turkey. The flames, which are known as Yanartas, have been burning for over 2500 years. Scientists now believe that ruthenium is partly responsible for this as when it is combined with methane, it may burn virtually forever.
What is the oxidizing temperature of niobium?
