摘要:

以氯化镍为母液、草酸铵为沉淀剂,用脉冲电磁场(PEMF)辅助草酸盐沉淀法制备了纤维状草酸镍盐。使用XRD、FT-IR、SEM以及激光粒度仪等手段分别表征了产物的物相、形貌和粒度,研究了脉冲电压、脉冲频率和脉冲处理时间等因素对草酸镍盐形貌和粒度的影响,并初步探讨了PEMF的作用机理。与未用PEMF处理的常规制备方法相比,该方法的加料速度由2 mL/min提高到5 mL/min;当脉冲电压为600 V、脉冲频率为4 Hz、脉冲处理时间为3 min时粉体的长径比由原来的7:1增加到25:1,且没有出现明显的团聚。适当的PEMF处理可使草酸镍盐的氨镍比为0.5~2.5,制备出较理想的纤维状形貌的草酸镍盐。

Abstract：

Fibrous particles of nickel oxalate salt were prepared by wet chemical method under the action of pulsed electromagnetic field (PEMF) using NiCl₂ solution as original liquid and (NH4)₂C₂O₄ solution as precipitant reagents, and which then were characterized by means of X-ray diffractometer (XRD), Fourier transform infrared spectrum (FT-IR), scanning electron microscopy (SEM) and laser granularity analyzer. The effect of PEMF parameters on the morphology and powder size of nickel oxalate salt was examined and the relevant mechanism model of interaction between PEMF and reaction system was preliminarily disccussed. Results show that in comparison to the conventional precipitation method, the feeding speed for the present process can be enhanced from 2 mL/min to 5 mL/min, and the aspect ratio of fibrous particles of nickel oxalate salt increased from 7:1 to 25:1 for the produced fibrous particles under PEMF with voltage 600 V, frequency 4 Hz and treatment time 3 min. Besides, not obvious agglomeration could be seen for the products. Finally, the desired fibrous particles of nickel oxalate salt could be prepared by a process in solutions with ammonia to nickel within a range of 0.5 to 2.5 and with appropriate PEMF parameters.
