Niobium合金和金属供应商

关于纯铌金属 (铌) 和铌合金

铌, 也被称为哥伦比亚, 是一种闪亮的灰色或银色延展性金属，在室温下不会变色或氧化. 铌仅在加热时与氧和卤素发生反应. 铌在高温下的耐腐蚀性不如钽。. 铌不受硝酸侵蚀的程度最高 100 ° C, 但受到硝酸和氢氟酸混合物的强烈攻击. 热的, 浓盐酸, 硫酸的, 磷酸会攻击它, 但是很热, 浓硝酸不.

铌在室温下不受大多数​​酸的影响. 在所有温度下都会受到碱性溶液的侵蚀. 由于热中子的俘获截面小, 铌在核工业中的应用. 铌可以电加热并阳极氧化成多种颜色，这使其在珠宝行业中非常有吸引力. 将铌添加到铁或镍中以制造航空航天中的合金, 医疗和电子行业.

What are the primary uses of Niobium?

应用程序: used in aerospace applications (i.e. rocket boosters), sodium vapor lamps, and superconductors. Niobium is used in the manufacture of synthetic diamonds; in sputtering targets for fiber optic applications or architectural glass; in nickel based superalloys; and alloyed with titanium or tin, in superconductors. In nuclear reactors it has low thermal neutron cross section and superior corrosion resistance, It is an excellent getter and finds use in high temperature vacuum furnaces, and is resistant to attack by the molten alkali metals found in sodium vapor lamps.

How does Niobium benefit steel production?

At atmospheric pressure, it has the highest critical temperature of the elemental superconductors. Niobium has the largest magnetic penetration depth of any element. High-energy physics researchers use some electron accelerators that include chambers cast from pure or alloyed niobium.

What medical applications does Niobium have?

Niobium is used as an alloying agent and for jewelry. Other uses include adding small amounts to improve stainless steel, as an alloying agent in carbon and alloy steels and in non-ferrous metals to improve strength. It is key element in manufacturing jet engines and rockets.

Is Niobium a refractory metal?

是, Niobium is malleable, weldable, machinable and formable.

What superconductor applications is Niobium well suited for?

When chilled to near absolute zero, these niobium chambers become both highly magnetic and superconducting, which permits researchers to increase the speed of subatomic particles without using increasing amounts of electricity.
