Overview of High Purity Nb Powder Niobium Powder 99.9%
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 Nb Powder Niobium Powder 99.9%
-
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 Nb Powder Niobium Powder 99.9%
The specific high purity Nb powder with a theoretical purity of 99.9% can vary depending on the suppliers and their processes. However, generally speaking, the most commonly used Nb powder for nuclear applications is in the form of a superdoped material called “superlithium niobium carbide” (SNC) or “superlithium nitride carbide” (SLN).
SNC has been widely used in the nuclear industry due to its high melting point and thermal stability, as well as its excellent radiation resistance properties. Theoretical purity of SNC ranges from 98.5% to 99.0%, but practical purity is typically around 99.5%.
SLN, on the other hand, has lower thermal stability than SNC, which means it can easily break down at higher temperatures. Nevertheless, SLN also has excellent radiation resistance properties and can be used in a variety of applications such as medical imaging, semiconductor manufacturing, and power generation.
Overall, the high purity Nb powder with a theoretical purity of 99.9% can be obtained through advanced processing techniques such as sintering, precipitation, or chemical vapor deposition.
