Abstract

Noble metal borides RuB_1.1, RuB₂ and Ru₂B₃ have been synthesized by mechanical alloying and high pressure sintering methods using ruthenium (Ru) and boron (B) powders as raw materials. The crystal structures of borides were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results shown that only RuB_1.1 with hexagonal crystal structure was synthesized during the ball milling process, the orthorhombic RuB₂ was synthesized under high pressure (5 GPa) and high temperature (1000 °C) conditions, while the hexagonal Ru₂B₃ can be synthesized under 5 GPa and 1200 °C. The mechanism of synthesis for the ruthenium borides (RuB_x) are discussed in details.
