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.

研究了温度、pH值、加料速度、浓度、[NH_3]_T/_T摩尔比、表面活性剂及其添加量、搅拌等对颗粒形貌与粒度的影响，主要结论为：(1)草酸镍化合物种类是决定颗粒形貌与粒度的最主要因素；(2)提高陈化中溶解—再结晶速度，有利于得到物相单一，形貌规整，轴向比大的粉末；(3)不同条件下，颗粒形核与生长过饱和度改变，也会对粉末形貌与粒度产生一定影响；(4)适量添加PVP25有利于大轴向比纤维状草酸镍的制备。3纤维状草酸钴的形成机理及其形貌与粒度控制采用CoCl_2溶液与(NH_4)_2C_2O_4和NH_3·H_2O混合溶液并流加料合成的方法，研究了纤维状草酸钴的制备。
