Pemasok Paduan & Logam Niobium

Tentang Logam Niobium Murni (Nb) dan Paduan Niobium

Niobium, juga dikenal sebagai Columbium, adalah logam ulet berwarna abu-abu atau keperakan mengkilat yang tidak ternoda atau teroksidasi pada suhu kamar. Niobium bereaksi dengan oksigen dan halogen hanya jika dipanaskan. Niobium kurang tahan korosi dibandingkan tantalum pada suhu tinggi. Niobium tidak diserang oleh asam nitrat hingga 100 ° C, tetapi secara agresif diserang oleh campuran asam nitrat dan fluorida. Panas, klorida pekat, sulfat, dan asam fosfat menyerangnya, tapi panas, asam nitrat pekat tidak.

Niobium tidak terpengaruh pada suhu kamar oleh sebagian besar asam. Itu diserang oleh larutan alkali sampai batas tertentu di semua suhu. Karena penampang tangkapan rendah untuk neutron termal, Niobium memiliki aplikasi dalam industri nuklir. Niobium dapat dipanaskan dengan listrik dan dianodisasi ke berbagai macam warna yang membuatnya sangat menarik di industri perhiasan. Niobium ditambahkan ke besi atau nikel untuk menghasilkan paduan di ruang angkasa, industri medis dan elektronik.

What are the primary uses of Niobium?

Aplikasi: 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?

Ya, 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.
