Description
Silicon Nitride (Si₃N₄) Nanopowder / Nanoparticles – Amorphous (99.5%, 20–35 nm)
Silicon Nitride (Si₃N₄) nanoparticles are ultra-hard ceramic nanomaterials with exceptional wear resistance, thermal stability, and chemical inertness. Produced in amorphous form with 99.5% purity and an average particle size of 20–35 nm, these nanoparticles exhibit a white color, spherical morphology, and high surface area (40–125 m²/g).
Manufactured via Plasma Arc Vapor method, Si₃N₄ nanopowder demonstrates excellent dispersibility (zeta potential: -21.5 mV) and superior mechanical properties, making it an ideal choice for aerospace, metallurgy, energy, and structural applications.
