Product Overview

Niobium Pentoxide (Nb?O?) 99.9% AR is a high-purity, white crystalline powder widely used in advanced laboratory and industrial applications. This reagent-grade material is characterized by its exceptional thermal stability, making it ideal for high-temperature processes. Its fine particle size ensures uniform dispersion in formulations, while the 99.9% assay guarantees minimal impurities, critical for sensitive applications. The compound exhibits excellent dielectric properties, making it valuable in electronic and optical materials. Its catalytic activity is leveraged in chemical synthesis, particularly in oxidation reactions. The AR (Analytical Reagent) grade ensures consistency and reliability in experimental results. Niobium Pentoxide is insoluble in water but soluble in hydrofluoric acid and alkaline solutions, offering versatility in various chemical environments. The product is packaged in airtight containers to prevent moisture absorption and contamination, ensuring long-term stability. Whether used in ceramics, glass manufacturing, or as a precursor for niobium-based compounds, this high-purity oxide delivers consistent performance for demanding laboratory requirements.

FAQs

1. What is the particle size range of this Niobium Pentoxide?

The typical particle size ranges between 1-5 microns, though exact distribution may vary slightly between batches. This fine particle size ensures excellent reactivity and homogeneity in mixtures.

2. Can this grade be used for thin-film deposition?

Yes, the 99.9% purity and fine powder form make it suitable for physical vapor deposition (PVD) and other thin-film applications where high purity is required to prevent defects.

3. How should Niobium Pentoxide be stored to maintain its purity?

Store in a cool, dry place in its original sealed container. Exposure to humidity should be minimized as the powder can absorb moisture, potentially affecting its performance in sensitive applications.

4. Is this product compatible with standard laboratory glassware?

While chemically stable, prolonged contact with glass at high temperatures may cause slight etching. For critical applications, consider using PTFE or other inert containers when handling at elevated temperatures.

5. What alternatives exist if I need a different purity level?

Lower purity grades (99.5% or 99%) are available for less demanding applications, while 99.99% purity options exist for semiconductor or high-end optical uses, though these typically come at a higher cost.
