Product information "4μm Silicon powder 3N, min. 99.9 %, 7440-21-3, super fine"
This silicon powder is mechanically produced from high-purity starting material with at least 99.9% silicon. The very small particle size gives the material increased reactivity and sintering activity, making it particularly interesting for ignition systems, gas generators, technical ceramics, and high-temperature applications. It is also ideally suited for the production of silicon nitride or silicon carbide. Chemical analysis (typical values): Si: > 99.9% Al: 351.3 ppmw Ca: 70.9 ppmw Fe: 75.4 ppmw Ti: 5.1 ppmw P: 1.8 ppmw Cu: 16.2 ppmw Cr: 2.6 ppmw K: 6.9 ppmw V: 0.1 ppmw Ni: 1.5 ppmw Na: 14.7 ppmw
Particle size distribution (typical values):
- D90 7.92 µm
- D50 4.16 µm
- D10 1.33 µm
Signal word: ATTENTION!
