Overview of High Purity CAS 12034-77-4 Niobium Selenide NbSe2 Powder
Niobium, often found in conjunction with tantalum minerals, is primarily extracted as a byproduct of tin and tantalum mining. Its chief ores include pyrochlore and columbite. Once refined, niobium becomes highly versatile, finding application in alloys, superconductors, and various high-tech materials.
Feature of High Purity CAS 12034-77-4 Niobium Selenide NbSe2 Powder
-
Superior Strength and Lightness: When added to steel in small quantities (typically less than 1%), niobium significantly enhances the strength and toughness of the alloy while reducing its weight, making it ideal for aerospace and automotive applications.
-
Corrosion Resistance: Like tantalum, niobium forms a passive oxide layer that protects it from corrosion, making niobium-based alloys suitable for use in harsh environments.
-
Superconductivity: Niobium exhibits excellent superconducting properties when cooled below its critical temperature of about 9.2 K (-264°C or -443°F). This property makes it the primary material for superconducting magnets used in MRI scanners and particle accelerators.
-
Magnetic Properties: Niobium is paramagnetic at room temperature but becomes strongly diamagnetic when cooled, meaning it repels magnetic fields. This characteristic is exploited in certain specialized applications.
-
Ease of Fabrication: Despite its strength, niobium is easily formed, welded, and machined, facilitating its use in complex engineering designs.

Parameters of High Purity CAS 12034-77-4 Niobium Selenide NbSe2 Powder
The formula for the high-purity CAS number 12034-77-4 Niobium Selenide (NbSe2) powder is:
[NiOSe2]·nH2O
Where:
NiOSe2: Niobium selenide monohydrate (selenide form)
n: amount of powder in grams
H2O: water
The atomic number and mass of niobium, which is used as the reference element in this formula, are both 59.
So, if you want to find the equivalent weight of the powder, you can use the following conversion factor:
[ NiOSe2 ]·n H2O = m(Oxide)
where:
m(Oxide): total weight of the oxide ions in the powder, in g/mol
For example, if you have 100g of the powder, you would convert it to moles using the formula above:
m(Oxide) = n × m(Oxide per mole) = 100g / 160.98 g/mol ≈ 0.625 mol
Then, you can calculate the equivalent weight of the powder in grams by multiplying by the appropriate weight unit:
w(NbSe2) = m(Oxide) × w(Oxide per gram) = 0.625 mol × 65.42 g/mol ≈ 434.7 g
Therefore, the equivalent weight of the high-purity CAS number 12034-77-4 Niobium Selenide (NbSe2) powder is approximately 434.7 grams.
