Preparation of Zinc Nanoparticles by Gas Condensation in a Contactless Crucible

In this work, zinc nanoparticles were obtained. As a production method, a one-stage induction flow levitation method was used. The starting material was spherical granules with a purity of 99.9% and a mass of 2 g; as atoms evaporated from the surface of the molten granule, the drop was fed with a metal wire made of the same material. The productivity of the nanoparticles was 30 g / h. The resulting nanoparticles were characterized by scanning electron microscopy, X-ray phase analysis, porosimetry, and inductively coupled plasma atomic emission spectroscopy.
