Abstract

Nanocrystalline silver (Ag) particles were prepared by ultrasonic spray pyrolysis (USP) method using silver nitrate aqueous solution. The dependence of morphology, particles and crystalline sizes to the carrier gas (H(2), N(2) and air) were investigated under 1.0 l/min gas flow rate, 0.1M precursor concentration, 600 degrees C reaction temperature and 1.3 MHz ultrasonic frequency conditions. Scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD) were used to investigate size, morphology and crystal structure of particles. It was observed that nanocrystalline spherical Ag particles obtained in all conditions with crystalline sizes are nearly 39 nm which are calculated by Schrrer equation.
