Product Overview
This 99.8% pure tellurium powder is meticulously processed to a -200 mesh particle size, ensuring exceptional uniformity and reactivity for demanding laboratory applications. The trace metal basis certification guarantees minimal metallic impurities, making it suitable for experiments where contamination could compromise results. The fine powder form allows for precise weighing and homogeneous mixing in various formulations. Tellurium’s unique properties, including its semiconductor characteristics and catalytic potential, make this high-purity grade particularly valuable for specialized applications. The product is packaged under controlled conditions to maintain its purity during storage and handling. Each batch undergoes rigorous quality control to verify the stated purity level and particle size distribution. The -200 mesh specification indicates that all particles pass through a 200-mesh screen, providing consistent performance in repeated experiments. This grade of tellurium powder represents an optimal balance between purity and practical usability for laboratory environments.
FAQs
1. What does “trace metal basis” mean for this tellurium powder?
Trace metal basis indicates that the purity percentage excludes other metallic impurities, which are measured and accounted for separately. This means the 99.8% purity refers specifically to the tellurium content when considering only metallic contaminants.
2. How should this fine tellurium powder be stored to maintain its properties?
Store in a tightly sealed container in a cool, dry place away from direct sunlight and moisture. The fine powder form makes it particularly sensitive to environmental conditions that could affect its purity or flow characteristics.
3. Is this tellurium powder compatible with standard laboratory glassware?
Yes, this powder can be safely handled with standard borosilicate glass laboratory equipment. However, always use appropriate personal protective equipment when handling fine metal powders to prevent inhalation or skin contact.
4. What’s the significance of the -200 mesh specification?
The -200 mesh designation means all particles will pass through a 200-mesh screen (with openings of 74 microns). This fine particle size ensures better reactivity and more uniform distribution in mixtures compared to coarser grades.
5. Are there any special handling precautions for this high-purity tellurium?
While tellurium is generally stable, this fine powder form may present additional handling considerations. Work in a well-ventilated area or fume hood, use anti-static measures to prevent dust accumulation, and avoid creating dust clouds that could pose inhalation risks.
