## Description

- description: A single-phase RuB2 (orthorhombic, space group Pmmn) polycrystalline
    material was successfully synthesized by the arc melting method. The condition
    for obtaining a single-phase RuB2 material is dependent on the composition and
    form of the raw materials, namely using the composition of atomic ratio Ru:B =
    1:2.1 and using granules Ru and B as the raw materials. The lattice constants
    of a single-phase RuB2 obtained by the arc melt method are a = 4.645(1), b = 2.865(1),
    c = 4.046(1) Å, V = 53.8(1) Å3. A thermogravimetric-differential thermal analysis
    (TG-DTA) for RuB2 was carried out from room temperature to 1473 K. The oxidation
    reaction of RuB2 begins at about 570 K, and the weight gain rate of final oxidation
    is 29%. Interestingly, the RuB2 material was found to have a significantly lower
    oxidation resistance than Ru metal. The product after heating up to 1473 K in
    air atmosphere is a mixture of RuB1.1 (RuB) and Ru phases, and B2O3 which is probably
    produced in an amorphous state. The values for electrical resistivity of RuB2
    are in the ranges from 23.3 × 10−3 to 102.2 × 10−3 Ω ‧ cm.
