In the present work, the mechanism of nickel coating on BN particles by hydrazine reduction was studied. A nickel sulfate - ammonium sulfate - ammonia - hydrazine hydrate plating system was employed. It was found that Pd on the surface of BN particles acted as an active center for nickel deposition at the initial stage of the process. Thereafter, Ni itself would act as an active center to catch Ni from the solution through the reaction: Ni2+, + 2H(ad)(*) double right arrow Ni + 2H(+). The rate of the process was found to be controlled by the reaction at the interface under the present experimental conditions. A kinetic model was proposed on the basis of the experimental results. The model predictions were found to be in agreement with the experimental data.
