研究了合成pH值、合成温度、陈化温度、干燥温度对球形Ni(OH) 2 物理性能的影响 ,结果表明 :要制得物理性能较好 (BET比表面、d0 0 1、FWHM10 1、I0 0 1/I10 1值较大 ,SO2 -4等杂质含量低 )的球形Ni(OH) 2 ,控制合成pH值为 11 0～ 11 30、合成温度为 5 0～ 6 0℃左右、陈化温度为 6 5～ 80℃、干燥温度在 115℃～ 135℃范围内较为适宜
The effects of pH value, synthesis temperature, aging temperature and drying temperature on the physical properties of spherical Ni (OH) 2 were investigated. The results showed that the physical properties of spherical Ni (OH) 2 were better 0 1 / I10 1 value is large, SO2 -4 and other impurities low) of spherical Ni (OH) 2, the control synthesis pH value of 11 0 ~ 11 30, the synthesis temperature is about 50 ~ 60 ℃, the aging temperature For 6 5 ~ 80 ℃, the drying temperature in the range of 115 ℃ ~ 135 ℃ is more appropriate
