摘要： 以硫酸盐为原料，添加NaOH溶液和NaHCO3粉末，先制备碱式碳酸盐前驱体，350℃空气中焙烧1 h后，制备出复合锌镍铁氧体纳米晶体. 经XRD和TEM分析，粒径约为30 nm，粒度较均匀. 通过改变原料中锌盐与镍盐的配比，制备出Zn0.9Ni0.1Fe2O4, Zn0.8Ni0.2Fe2O4, Zn0.7Ni0.3Fe2O4, Zn0.6Ni0.4Fe2O4和Zn0.5Ni0.5Fe2O4 五种纳米粉.

Abstract: ZnxNi1-xFe2O4 nanosized powders were prepared by calcined basic carbonate precursor synthesized from solid FeSO4×7H2O, NiSO4×6H2O, ZnSO4×7H2O, NaHCO3 salts and concentrated NaOH solution, then the precursor was calcined at 350oC for 1 h. The microstructure of the obtained sample was examined by XRD and TEM analyses. The results show that the size of nanocrystalites is about 30 nm. Changing proportion of ZnSO4×7H2O and NiSO4×6H2O, nanocrystalline Zn0.9Ni0.1Fe2O4, Zn0.8Ni0.2Fe2O4, Zn0.7Ni0.3Fe2O4, Zn0.6Ni0.4Fe2O4 and Zn0.5Ni0.5Fe2O4 were also prepared.

Key words: ZnxNi1-xFe2O4, nanosized powder, preparation experiment
