Product Overview
This high-purity bismuth powder (-325 mesh) offers 99.5% metal basis purity, delivering exceptional performance for demanding laboratory applications. The ultra-fine particle size ensures uniform dispersion and reaction efficiency, making it particularly valuable for precision metallurgical processes and specialized chemical synthesis. Bismuth’s unique properties—including its low toxicity compared to other heavy metals, high density (9.78 g/cm³), and distinctive thermal expansion characteristics—make this powder an essential component in advanced material science applications. The powder maintains excellent stability under normal storage conditions and exhibits minimal oxidation when properly handled. Its fine mesh size enables precise dosage control in experimental setups while maintaining consistent batch-to-batch performance. The material’s high purity level minimizes impurities that could affect experimental outcomes, particularly in sensitive analytical procedures. This bismuth powder represents an optimal balance between purity, particle size distribution, and cost-effectiveness for research environments requiring reliable metal powders.
FAQs
1. What particle size distribution can be expected with -325 mesh bismuth powder?
The -325 mesh designation indicates that all particles pass through a 325-mesh screen, meaning the maximum particle size is approximately 44 microns. The actual distribution typically shows 90% of particles between 10-40 microns with a median around 25 microns, though exact distribution may vary slightly between batches.
2. How does the 99.5% purity compare to other available bismuth powder grades?
This 99.5% metal basis purity represents a high-grade material suitable for most research applications. It contains significantly fewer impurities than commercial grades (typically 99.0% or lower) while offering better cost efficiency than ultra-high purity grades (99.99% or higher) that are generally reserved for semiconductor or specialized electronic applications.
3. What precautions should be taken when handling this bismuth powder?
While bismuth has low toxicity, standard laboratory precautions should be followed. Use in a well-ventilated area or fume hood, wear appropriate PPE including gloves and safety glasses, and avoid inhaling the fine powder. The material should be stored in a tightly sealed container away from oxidizing agents and moisture.
4. Is this bismuth powder compatible with standard laboratory glassware?
Yes, the powder can be safely used with borosilicate glassware and most common laboratory containers. However, for reactions involving strong acids or high temperatures, we recommend using PTFE-coated or other chemically resistant containers to prevent potential contamination from glass corrosion.
5. What is the typical shelf life of this bismuth powder when stored properly?
When stored in its original sealed container at room temperature (15-25°C) away from direct sunlight and moisture, this bismuth powder maintains its specified purity and physical properties for at least 24 months from the date of manufacture. The low oxidation rate of bismuth contributes to its excellent storage stability compared to other metal powders.
