油酸包覆下的纳米Fe_3O_4材料的制备及温度对粒径的影响

Preparation of nanometer Fe_3O_4 material covering by oleic acid and effect of temparature to particle size

在Fe3O4的制备过程中,温度对Fe3O4粒径的影响至关重要的因素。本实验采用油酸作为分散剂,利用化学共沉淀法,在适当的温度下以高速搅拌的方法制备纳米级Fe3O4。并就温度对Fe3O4粒径的影响进行了分析。

The temparature is a key effect to Fe3O4 particle size in preparation. The nanometer Fe3O4 material was prepared by chemical coprecipitation method and using oleic acid as dispersant, with high speed stiring under proper temparature. The effect of temparature to particle size was analyzed.
