| description | To provide an iron particle, a molded product, and a manufacturing method of the iron particle which can efficiently block electromagnetic waves while preventing reflected waves from being generated.SOLUTION: An iron particle 1 includes iron 2, and an oxide film 3 composed of triiron tetroxide that covers the iron 2. The iron particles 1 are charged into a molded body of a synthetic resin. A manufacturing method of the iron particle 1 includes a recovery step of recovering the iron particle 1 formed by iron processing and a conversion step of converting diiron trioxide that coats the iron particle 1 recovered in the recovery step into triiron tetroxide.SELECTED DRAWING: Figure 1
【課題】反射波を生じさせないようにしつつ、電磁波を効率的に遮蔽することができる鉄粒子、成形体及び鉄粒子の製造方法を提供する。【解決手段】鉄粒子１は、鉄２と、鉄２を覆う四酸化三鉄で構成される酸化皮膜３と、を備える。鉄粒子１は、合成樹脂の成形体内に充填される。鉄粒子１の製造方法は、鉄加工で生成される鉄粒子１を回収する回収ステップと、回収ステップで回収された鉄粒子１を皮膜する三酸化二鉄を四酸化三鉄に変換する変換ステップと、を含む。【選択図】図１ |
