“…In industrial production, considering the required separating density, viscosity and stability of the system, the selected weighting agents should have high density, be difficult to make muddy and to oxidize, and be easy to recycle 5 . In principle, media with a density higher than that of water can be used as the weighting agents 6 . Currently, the commonly used weighting agents in industry are magnetite, ferrosilicon, ilmenite, barite, pyrite and industrial waste, such as reduced iron and magnetic beads, which were industrially used by Hamidreza et al 7 and experimentally used by Ramadan et al 8 respectively.…”

Ferrosilicon powder surface coated with a dense epoxy resin membrane was prepared via coating precipitation methods using silane coupling agents as the modifier and epoxy resin as the coating agent. FTIR, FESEM, MPMS-XL, and TG-DSC were used to analyze the morphology, surface composition, magnetic property and thermostability of ferrosilicon powder before and after the modification and coating. The experimental results indicate that epoxy resin membranes of a certain thickness were successfully coated onto the surface of ferrosilicon powder; coatings of epoxy resin contributed to the decreased the rate of weight loss via the reduced wear of the coatings and provided resistance to corrosion; the apparent viscosity of medium suspension with coated ferrosilicon was smaller than that of magnetite. Meanwhile, analysis reveals that room-temperature magnetic hysteresis loops of ferrosilicon powder remain basically unchanged before and after coating.
