N2 - Ultrafine copper powders with an average size of 150 nm were synthesized by chemical reaction from Cu(OH)2 H2O slurry with hydrazine monohydrate as a reduction agent. Parameters such as temperature, reduction agent feeding rate, stirring rate, stirring speed, Cu(OH)2 concentration, and surfactants were investigated. It was found that the feeding rate of hydrazine monohydrate and the use of surfactants mainly affect the morphology and size of the copper powders along with their dispersion. XRD, PSA, and SEM were used to characterize the prepared particles.
