Fine nickel powders have been prepared by chemical reduction between nickel acetate and alcohol under solvothermal conditions. The effect of adding surfactant and varying solvent on the particle size of the as-synthesized nickel powders have been explored. SEM, XRD and TG were employed to characterize the size, morphology, crystalline structure and the thermal stability of the as-synthesized nickel powders. It is revealed that the FCC-structured nickel powders are of uniform spherical shape with good crystallinity and thermal stability. Typically, nickel powders with an average size of 300 nm were obtained at 200°C for 8 h using 0.04 mol/L solution of Ni(CH3COO)2·4H2O in n-butyl alcohol under solvothermal conditions.

Aiming at flexible oxidation in the MLCC production, the surface modification of the ultrafine nickel powders has been carried out to coat Ni powders with CaZrO3 by using chemical precipitation method. CaZrO3-coated composite ultrafine nickel powders have been synthesized in methanol-water solvent by both precipitation agents solution and zirconium-calcium solution dripped into the Ni-particle-dispersed methanol solution at the meantime. Composite nickel powders obtained under the optimum conditions were characterized, It was approved that those composite nickel powders still possessed good dispersion, the resistance to oxidation and shrinkage were improved greatly.
