Preparation of Ag Nanoparticles in Ammonia by Using EDM and a Study of the Relationships Between Ammonia and Silver Nanoparticles

摘要: This study used deionized water and ammonia (0.02%) as dielectric fluids then employed electronic discharge machine to ionize them, with the arc-focused energy melting surface of silver electrode rods. After condensation fluid, nano-colloids were prepared under two conditions, named Ag Ag(NH3), respectively. The optical properties samples compared by a UV–Vis spectrum analyzer (UV–Vis), zeta potential was measured Zetasizer. We utilized transmission electron microscope observe shape, size, distribution nanoparticles. results showed that addition NH3, size nanoparticles decreased, concentration nano-colloid increased, dispersive suspension became better.
