Abstract

To prepare Ni (OH)2 of high electrochemical activity and bulk density , with urea and nickel nitrate as the raw materials , the ultrafine particles of nickel hydroxide is prepared with homogeneous sendimentation method . The optimum processing conditions are found through desinged orthogonal experiments .Microstructure and morphology of nickel hydroxide are investigated by means of IR, XRD and SEM.The results indicate that highyield and fine granular nickel hydroxide can be achieved when the temperature is above 95 ℃ and the mol rate of urea and nickel nitrate is 3∶1 .Nickel hydroxide power in the diameter of 0.4 ～ 0.5 m is available by controlling reaction conditions .[ Ch , 6 fig .5 ref .]
- nickel hydroxide,
- homogeneous precipitation method,
