## Description

- description: 'High-aspect-ratio ZrB2 rod crystals were synthesized via a molten-salt-mediated
    boro/carbothermal reduction using ZrOCl2⋅8H2O/B4C/C as the raw material and NaCl
    as the flux material. This synthesis may improve the poor fracture toughness of
    monolithic ZrB2 ceramics. X-ray diffraction and scanning electron microscopy confirmed
    that the heat-treatment temperature of 1550 ◦C and the addition of 50 wt% NaCl
    were the most effective in the preparation of ZrB2 grains with a high aspect ratio.
    Thermogravimetric and differential scanning calorimetry was used to study the
    influence of NaCl addition, which increased the liquid-phase content. Finally,
    the growth of ZrB2 grains along the c-axis into rod-like morphology at elevated
    temperatures was investigated by transmission electron microscopy. This work revealed
    that the addition of NaCl has a positive effect on the reducing of synthesis temperature
    and increasing of products particle size. '
