Niobium Metal Nb CAS 7440-03-1 For Superconducting Alloy Additives

The metal niobium (chemical symbol Nb, atomic number 41) is an important transition metal element with a wide range of applications. As a gray metal, niobium has excellent physical and chemical properties. In terms of superconducting materials, niobium has a low superconducting temperature but superior performance, and is used in the manufacture of superconducting cables and magnets. In addition, niobium also has good corrosion resistance and ductility, and is widely used in chemical equipment and Marine engineering.

Niobium can also be alloyed with other metal elements to make high-strength and corrosion-resistant alloys, which are widely used in aerospace, automotive and mechanical fields. In the electronics industry, niobium is used in the manufacture of capacitors, resistors and other components to improve the electrical performance of equipment. The medical field also uses niobium's biocompatibility and wear resistance to make medical devices such as artificial joints and dental implants.

Description

Niobium is a soft gray silver metal similar to freshly cut steel. Because of niobium oxide thin coating, it will not change color at room temperature or oxidize in air, but it is easy to oxidize at high temperature (higher than 200°C), especially by oxygen and halogen. Niobium is the 33rd most abundant element in the earth's crust and is considered to be a rare element. It does not exist in the form of free element metals in nature. It is mainly found in several ores. Niobium exists in niobite (or cobaltite), niobium tantalite, pyrochlore and Sumeria. The method of extracting and refining niobium from ore. The method chosen depends on the nature of the ore and the end use of the metal. Some common steps in these recovery processes include ore preconcentration, ore crushing or opening, obtaining pure niobium compounds, reducing niobium compounds to niobium metals, purifying or refining metals, and manufacturing.

Used

Niobium, as an additive or alloy with other metals, can give the alloy high mechanical strength, high conductivity and ductility. It enhances the corrosion resistance of most alloys. This metal and several of its alloys exhibit superconductivity. Niobium can be used as an additive in the manufacture of high strength, low alloy carbon steel and microalloyed steel. It is also added to nickel base and cobalt base superalloys, and is an integral part of zirconium, titanium and tungsten alloys. Other applications of niobium are in electronics and propulsion, in electrodes; catalysis, as well as vacuum tubes and high-pressure sodium vapor lamps.
