【摘要】 采用沉淀转化法制备了氢氧化镍超微粉 ,并对表面活性剂的浓度、pH值及转化温度等实验参数对氢氧化镍粉末组成和结构的影响作了较细致的研究。实验结果表明 :当转化温度为 60℃ ,表面活性剂浓度为 15ml·L- 1 ,pH值为 11.0～ 12 .0时 ,所得样品为球形 ,粒径约 2 0 0nm左右更多还原

【Abstract】 Ultrafine powers of nickel hydroxide was prapared by precipitation transform method in the paper.The influence of concentrations of surfactant and pH and transformation temperature on phase composition and structure were studied in detail.The experimental results showed that,when transformation temperature was 60℃,the concentrations of surfactant was 15 ml·L -1 ,pH is in the range of 11.0～12.0,shape of nickel hydroxide with 200nm is spherical.更多还原
