摘要
以Span60 正己醇 环己烷 水为微乳液体系 ,制备γ Fe2 O3纳米微粒。研究了不同灼烧温度对γ Fe2 O3结构和磁性的影响。通过XRD、IR和磁化率的测定表明 ,在40 0℃下的磁性最大 ,70 0℃以上灼烧的γ Fe2
Nanoparticles of γ Fe 2O 3 were prepared by microemulsion composed with the system of Span60 n hexanol Cyclohexance Water.The effect of fire temperature on the magnetism of γ Fe 2O 3 has been investigated.Analysis of the XRD,IR and susceptibility results shown that the single particle size is 0 86 to 1 72nm.The largest susceptibility is under the temperature at 400℃,the magnetism is nearly disappeared when the temperature is over about 700℃.
