摘要
采用硬脂酸凝胶法制备NiFe2O4纳米晶,用TG-DTA、XRD和TEM对产物进行表征,并与用共沉淀法制得的NiFe2O4粒子进行比较。结果表明,用硬脂酸凝胶法制备NiFe2O4粒子粒度分布均匀,粒径小,无硬团聚现象。
In this paper,NiFe_2O_4 nanocrystalline particulates were prepared by stearic acid gel method.The products were characterized by TG-DTA,XRD and TEM and were compared with those fabricated by co-precipitation.The results showed that NiFe_2O_4 nanocrystalline prepared by stearic acid gel method had average distributed uniformity and small grain size without aggregation.
