Particles of Nickel hydrazine sulfate were synthesized by the reaction of NiSO4 with NH2NH2·H2O in the presence of deionized gelatin at low temperature.The results of X-ray powder diffraction showed that the particle was a pure nickel hydrazide sulfate compound.The morphology of the particle was characterized by transmission electron microscopy.The particle showed a porous spherical structure with an average diameter of 0.5~1.0μm.The reaction mechanism was also discussed.It provides reference for the synthes...
