Overview of CAS 1313-96-8 Niobium Oxide 99.99% Nb2O5

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 CAS 1313-96-8 Niobium Oxide 99.99% Nb2O5

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. Ease of Fabrication: Despite its strength, niobium is easily formed, welded, and machined, facilitating its use in complex engineering designs.

Parameters of CAS 1313-96-8 Niobium Oxide 99.99% Nb2O5

CAS 1313-96-8 is the chemical formula for Niobium oxide, which has a melting point of 4057°C and a boiling point of 4926°C. It has a density of 6.4 g/cm³ and a crystal structure of face-centered cubic (FCC).
The “99.99%” in this formula refers to the purity of the material. The % means that out of the total weight of the product, 99.99% of theNiobium oxide is present. This means that there is only one atom of niobium present in every gram of the material.
It’s important to note that this particular niobium oxide compound is a solid solution, meaning it consists of two phases: an n-type phase with a slightly negative charge and a p-type phase with a slightly positive charge. These two phases are called the “nodal layer” and the “p-n junction”. The p-n junction is responsible for conducting electricity through the material.
