Niobium合金和金屬供應商

關於純鈮金屬 (鈮) 和鈮合金

鈮, 也被稱為哥倫比亞, 是一種閃亮的灰色或銀色延展性金屬，在室溫下不會變色或氧化. 鈮僅在加熱時與氧和鹵素發生反應. 鈮在高溫下的耐腐蝕性不如鉭. 鈮不受硝酸侵蝕的程度最高 100 ° C, 但受到硝酸和氫氟酸混合物的強烈攻擊. 熱的, 濃鹽酸, 硫酸的, 磷酸會攻擊它, 但是很熱, 濃硝酸不.

鈮在室溫下不受大多數酸的影響. 在所有溫度下都會受到鹼性溶液的侵蝕. 由於熱中子的俘獲截面小, 鈮在核工業中的應用. 鈮可以電加熱並陽極氧化成多種顏色，這使其在珠寶行業中非常有吸引力. 將鈮添加到鐵或鎳中以製造航空航天中的合金, 醫療和電子行業.

What are the primary uses of Niobium?

應用程式: 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?

是的, 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.
