Preparation and chemical stability of iron-nitride-coated iron microparticles

Mechanistic Insights into the Phase Formation of an Atypical Iron Oxynitride (FexOyNz) System and Its Multifunctional Photocatalytic Applications

“…The observed weight increment with increasing temperature is estimated to be ∼29.56%, indicating that approximately 4.434 mol/g of nitrogen atoms is replaced with oxygen during this process. From these insights gained, the obtained iron nitride (FN) sample was annealed at various temperatures such as 200, 300, 400, 500, and 600 °C for 1 h in a normal ambience to understand the oxynitride phase tunability in the resulting system. , A plausible formation mechanism of the oxynitride phase, as suggested by thermal and XRD analyses (discussed in the following section), is depicted in Figure b.…”

Aspects Concerning the Fabrication of Magnetorheological Fluids Containing High Magnetization FeCo Nanoparticles

“…Concerning the magnetic filler (particle) to be added to the liquid carrier, the best performance was observed when they showed high saturation magnetization and magnetic permeability values, and low coercitivity strength [15,16]. That is soft magnetic particles.…”
