| Abstract: | Ultrafine nickel powders were prepared by controlling the condition of reductive reaction using ultrasonic-spray from nickel sulfate solution. The mechanism of reaction and the influence of ultrasonic spray, temperature of reaction, concentration of reactants, pH, and surfactant on the technological process, morphological and size of nickel powder were analyzed. The results show that particle sizes depending on the condition of reaction with spherical -like morphology were formed. |
