采用次亚磷酸钠化学还原法制备非晶态Ni-P合金粉末,并研究了镍离子浓度、pH值和温度对反应的影响。用X射线衍射仪(XRD)、扫描电镜(SEM)、震动样品磁强计(VSM)和X射线能谱仪(EDS)对样品进行了表征。结果表明,初始pH值为12,在70℃加入还原剂再升温到90℃,然后控制镍离子的浓度可制备出球形度高和分散性好的非晶态合金粉末,其磁性显示出超顺磁性。 Amorphous Ni-P alloy powders were prepared by chemical reduction of sodium hypophosphite, and the effects of nickel ion concentration, pH value and temperature on the reaction were studied. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), vibrating sample magnetometer (VSM) and X-ray energy dispersive spectrometer (EDS) The results showed that amorphous alloy powder with high sphericity and good dispersibility can be prepared by controlling the concentration of nickel ion at initial pH of 12, adding reductant at 70 ℃ and then heating to 90 ℃. magnetic.
