Common fields of niobium oxide: used for pulling nickel niobate single crystal, making special optical glass, high frequency and low frequency capacitors and piezoelectric ceramic components. It is also used in the production of various niobium alloys for ferroniobium and special steels. It is the raw material for the preparation of niobium and its compounds. Also used as catalyst, refractory.
Meltable products are: high-entropy alloys, copper alloys, aluminum alloys, zinc alloys, titanium alloys, zirconium alloys, low alloy steels, high alloy steels, superalloys, functional materials, refractory alloys and precious metals
It is mainly used for pulling lithium tantalate single crystal and manufacturing special optical glass with high refractive index and low dispersion. It can be used as catalyst in chemical industry.
Niobium chemical symbol Nb, atomic number 41, atomic weight 92.90638, belongs to the ⅤB group of the periodic system. In 1801, British C. Hatchet isolated an oxide of a new element from niobium iron ore, and named the element as columbium (the Chinese name is columbium). Niobium is an off-white metal with a melting point of 2468°C, a boiling point of 4742°C and a density of 8.57 g/cm3.
The master alloy is a kind of metal as the matrix, and one or several elements are added to it to solve the problems of easy burning, high melting point, difficult to melt, high density and easy segregation, or special alloys used to improve the properties of the alloy. is an additive functional material
