摘　　要：在醇 -水体系中采用沉淀法制成复合氢氧化物 ,再经高温煅烧制成纳米尖晶石型Zn FexCr(2 -x) O4粉体材料 ,并用XRD ,TEM和IR等方法对纳米晶进行表征。通过与传统的水溶液共沉淀法相比较 ,表明该方法得到的样品粉体粒径尺寸小。The spinel-type ZnFe x Cr (2- x )O 4 nanopowder was fabricated by calcining the composite of hydroxid synthesized in alcohol-aqueous solution.XRD,TEM and IR analyses show that the particles of the products obtained by the above method are of smaller size,narrower size distributions and less aggregation than those obtained from the ordinary powders synthesized by coprecipitation in water solution.
