摘要
分别采用共沉淀法、柠檬酸盐法和瞬时共烧法制备了磁性膨胀石墨样品;采用SEM、EDS能谱和磁滞回线研究了样品的微观形貌与性能。结果表明,采用柠檬酸盐法制备的膨胀石墨样品,铁氧体在表面和层间的沉积效果良好,磁性较强。
Co-deposition, citric acid sol-gel and instantaneous blended calcination methods are used to produce magnetic EG（exfoliated graphite）separately, The property and microcosmic performance of the magnetic exfoliated graphite samples are characterized by SEM, EDS and hysteresis loop. The results indicate that the samples produced by citric acid sol-gel method show better effection of precipitation and stronger magnetism.
