Product Overview

This high-purity tungsten powder features a -200+325 mesh particle size distribution, ensuring exceptional uniformity and reactivity for demanding laboratory applications. With a minimum purity of 99.95% on a metals basis, it delivers superior performance in thermal conductivity experiments and high-temperature environments. The ultra-fine powder form provides excellent surface area for chemical reactions while maintaining tungsten’s characteristic high density (19.3 g/cm³) and melting point (3422°C). The controlled particle size distribution eliminates variability in experimental results, making it ideal for precision research applications. The powder’s exceptional thermal stability and resistance to corrosion ensure reliable performance across multiple experimental cycles. Each batch undergoes rigorous quality control to maintain consistent purity and particle size distribution, providing researchers with dependable material properties for their critical work.

FAQs

1.

What is the typical particle size distribution for this tungsten powder?

The -200+325 mesh specification means the powder passes through a 200 mesh screen (74 microns) but is retained on a 325 mesh screen (44 microns), giving a controlled particle size range between 44-74 microns. 2.

Is this tungsten powder suitable for 3D printing applications?

While this grade offers excellent purity, 3D printing typically requires specialized tungsten powders with specific particle size distributions and flow characteristics that may differ from this standard laboratory grade. 3.

How does the 99.95% purity compare to other tungsten powder grades?

This 99.95% purity represents a high laboratory grade that exceeds most industrial grades (typically 99.5-99.9%) while being more cost-effective than ultra-high purity grades (99.99%) used in semiconductor applications. 4.

What precautions should be taken when handling this tungsten powder?

As with all fine metal powders, use in a well-ventilated area with appropriate respiratory protection, as the fine particles can become airborne. Store in a cool, dry place away from ignition sources. 5.

Can this tungsten powder be used for creating tungsten heavy alloys?

While possible, creating tungsten heavy alloys typically requires specific particle size distributions and may benefit from specialized alloying grades rather than this general laboratory grade.
