The effects of such parameters as temperature, pH, feeding rate,concentration, [NH_3]_T/_T molar ratio, surfactants and agitation, on the morphology and size of the particles, were studied and conclusions obtained are as follows:(1) The morphology and size of the particles are mainly decided by the species of nickel oxalates present.(2) Speeding up dissolution-recrystallization process benefits the preparation of the particles of being composed of a single species with uniform morphology and high aspect ratio.(3) The variations of nucleation and growth supersaturation under different conditions have definite effects on the morphology and size of the particles.(4) Adding PVP25 at a proper amount is beneficial to the preparation of fibrous nickel oxalate particles with high aspect ratio. 3 The formation mechanism as well as the morphology and size control of fibrous cobalt oxalate particlesThe cobalt oxalate particles with fibre morphology were prepared using CoCl_2 solution and mixed(NH_4)_2C_2O_4, NH_3·H_2O solution by a double jet process.
