Selective synthesis and magnetic properties of iron silicide (FeSi and FeSi) at low temperature

In this study, iron silicide (Fe 3 Si and FeSi) particles have been selectively synthesized through a solid-state reaction route. The reactions are carried out at 650 °C in a stainless steel autoclave using iron sesquioxide (Fe 2 O 3 ), elemental silicon and active metals (magnesium and lithium) as...

Description
Summary:In this study, iron silicide (Fe 3 Si and FeSi) particles have been selectively synthesized through a solid-state reaction route. The reactions are carried out at 650 °C in a stainless steel autoclave using iron sesquioxide (Fe 2 O 3 ), elemental silicon and active metals (magnesium and lithium) as reactants. The experimental results show that active metals are an important factor influencing the phase of the products. In addition, the magnetic properties of the products have been investigated. This method can provide a general route for the selective synthesis of other transition metal silicides. Iron silicide (Fe 3 Si and FeSi) particles have been selectively synthesized through a solid-state reaction route.
