摘要
将氢氧化铁 (Fe(OH) 3)粉末和可膨胀石墨粉末均匀混合 ,然后在高温下快速膨化。通过这种方法 ,使具有磁性的细小氧化铁颗粒比较均匀地分散在石墨基体中 ,从而得到了一种兼备导电性和亚铁磁性的复合材料 。
Residue sulfuric acid\|graphite intercalation compounds were mixed with Fe(OH)\-3.The mixture was rapidly heated to the ranged from 800℃ to 1200℃ by putting into furnace for 30 seconds.The resulted expanded graphite could be compressed into the flexible sheet,in which ferric oxide particles disperse.This kind of composite possesses high electric conductivity and good magnetic property,it is an excellent electromagnetic shielding material.
