Production of Nano NiO Particle with Chemical Precipitation Method and their Characteristics

Abstract:

Nano nickel oxide (NiO) particles were synthesized by a homogeneous precipitation method using NiCl2 as starting material and CO(NH2)2 as precipitant. Proper amount of NP-10 and appropriate organic solvent were added in the preparation process as dispersant. The chemical composition and properties were characterized by means of transmission electron microscope, X-ray diffractometer, and thermo gravimetry-differential thermal analyzer. The effects of reactant ratio, reaction temperature, reaction time, surfactant concentration, organic modifier concentration, agglomeration temperature as well as other reaction conditions on the appearances, size and dispersity degree of nano particles were investigated. The experiment results show that homogenous nano NiO particles were obtained by reacting nickel oxide and urea with a weight ration of 1:5 for 6 h at 80°C, then calcining for 2 h at 300°C. Adding surfactant NP-10 and organic solvent butanol to reaction system increases the dispersity and decreases the particle size of nano nickel oxide.
