純粋なニオブ金属について (Nb) およびニオブ合金

ニオブ, コロンビウムとしても知られています, 室温で変色または酸化しない光沢のある灰色または銀色の延性のある金属です. ニオブは、加熱された場合にのみ酸素およびハロゲンと反応します. ニオブは高温でタンタルよりも耐食性が低い. ニオブは硝酸に攻撃されません 100 ° C, しかし、硝酸とフッ化水素酸の混合物によって攻撃的に攻撃されます. ホット, 濃塩酸, 硫酸, そしてリン酸がそれを攻撃します, でも暑い, 濃硝酸はしません.

ニオブは室温でほとんどの酸の影響を受けません. それはすべての温度である程度アルカリ性溶液によって攻撃されます. 熱中性子の捕獲断面積が小さいため, ニオブは原子力産業に応用されています. ニオブは電気的に加熱し、さまざまな色に陽極酸化することができるため、ジュエリー業界で非常に魅力的です。. ニオブは、航空宇宙で合金を製造するために鉄またはニッケルに添加されます, 医療および電子産業.

What are the primary uses of Niobium?

アプリケーション: 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?

はい, 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.
