| 1. | This text attempts to regard silica as shell materials , regard nanometer iron and carbonyl iron particle as core materials to prepare a kind of new - type absorbent . the structur of the core - shell particles were characterized by ftir , tem , sem , xps , xrd etc . the properties of magnetism , heat , crystalization , ectromagnetic were characterized by vsm , tg - dta , network vectorial analysis instrument 本文以二氧化硅为壳层材料,以纳米铁以及羰基铁粒子为核层材料,制备一种新型的吸收剂粒子。用ftir , tem , sem , xps , xrd表征了复合粒子的结构,利用vsm , tg - dta ,网络矢量分析仪等分析了材料结构改变对材料磁性能,热性能,结晶性能,电磁参数等性能进行了分析。 |
