Synthesis and Characterization of Fe, Ru and Os Metal Borides

Omar Ali Al-Zain and Al-Masoudi Reem Soliyman

Direct reaction of Fe2O3 at 500, 700 and 1000°C for two, two and 15 h, respectively, with elemental boron in a muffle furnace yielding black beautiful nanorods of FeB crystals with high yield of 72% (as proved by xrd, tem and Magnetic hysteresis). Going down the group of the transition metals RuCl3 and OsCl3 reacted directly with elemental boron in a muffle furnace at 500, 700 and 1000°C for two, two and 15 h, respectively yielding nanorods crystals (as proved by xrd, tem and Magnetic hysteresis) of RuB2, Ru2B3 (yield was 68%) and OsB2 (yield was 56%).
