摘要
用溶胶法制备出了Fex－（SiO2）100-x纳米复合材料，并就制作工艺中酸度对材料的磁性参数的影响，作了类比实验及分析，逐步地改进了实验方法，取得了较好的效果．
Granular Fe-SiO2 solid has been prepared by using a sol-gel method.the effect of acidity on the magnetic properties of nanocrystalline Fe-SiO2 solid has beeninvestigated. By improving experimental method gruadually, the sample with excellentproperties was fabricated successfully.
