Patent ID: 8480784

Claim:
A method of producing a silver nanopowder using electromagnetic levitation process, the method comprises: designing a levitation chamber; selecting a suitable levitation coil; placing the levitation coil around the levitation chamber; placing a silver sample in an electromagnetic field of the levitation coil at an atmospheric pressure to levitate and melt the silver sample simultaneously; heating the levitated and melted silver sample at a constant temperature to produce a vaporized precursor material and wherein the vaporized precursor material is a silver vapor; blowing a carrier gas at a preset rate at a room temperature to cool and condense the silver vapor into a silver nanopowder to obtain a silver nanoparticle; collecting the silver nanoparticle in an inert media to obtain a dilute suspension of the silver nano particles in the inert media in an airtight container by blowing said carrier gas at a room temperature and wherein the inert media is a pure n-hexane.
