Silicon Nitride (SiN) Nanoparticles, nanodots or nanopowder are spherical high surface area particles. Nanoscale Silicon Nitride Particles are typically 10 - 100 nanometers (nm) with specific surface area (SSA) in the 25 – 75 m 2 /g range. Nano Silicon Nitride Particles are also available in ultra high purity and high purity and coated and dispersed forms. Research into applications for Silicon Nitride nanocrystals includes use as a superbase catalyst, in solar cell applications, as a substrate and for use in other coatings, plastics, polymers and wire. Silicon Nitride Nano Particles are generally immediately available in most volumes.
