## Description

- description: 'In this work, we report a rapid synthesis method for polycrystalline
    transition-metal tetraborides using reactive spark plasma sintering (R-SPS). This
    method was demonstrated on the synthesis of single-phase manganese tetraboride
    (MnB4) in a short time, 30 minutes. Starting powders with variable B/Mn molar
    ratios (4.1, 4.5, 5.0, and 8.0) were subjected to 12 h of high-energy ball milling
    (HEBM), followed by synthesis and consolidation in a single step using R-SPS in
    a dynamic vacuum atmosphere. Phase purity was confirmed by powder X-ray diffraction
    (PXRD); single-phase MnB4 was obtained for B/Mn molar ratio of 4.5 and higher
    in the temperature range of 850 – 1080°C, while the lower B/Mn molar ratio (4.1)
    resulted in a mixed-phase (Mn3B4 + MnB4) sample. The crystal structure and lattice
    parameters estimated from PXRD agree well to those reported for single-crystal
    MnB4. Thermogravimetric differential thermal analysis (TG/DTA) revealed that MnB4
    is stable in air up to 400°C. '
