關於Pure Niobium Metal (鈮) 同鈮合金

鈮, 也稱為桎梏, 是一種有光澤的灰色或銀色延展性金屬，在室溫下不會失去光澤或氧化. 鈮僅在加熱時與氧氣和鹵素反應. 徜徉在高溫下的耐腐蝕性不如徜徉. 鈮不受硝酸侵蝕，最高可達 100 °C, 但受到硝酸和氫氟酸混合物的猛烈攻擊. 熱, 濃鹽酸, 硫酸, 磷酸會攻擊它, 但好熱, 濃硝酸不.

鈮在室溫下不受大多數酸的影響. 在所有溫度下，它都會喺一定程度上受到鹼性溶液嘅侵蝕. 由於其對熱中子嘅捕獲截面較低, 鈮喺核工業中有應用. 鈮可以電加熱和陽極氧化成多種顏色，使其在珠寶行業中非常有吸引力. 鈮被添加到鐵或鎳中以喺航空航天中生產合金, 醫療和電子行業.

What are the primary uses of Niobium?

應用: 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?

係, 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.
