## Description

- description: 'This study reports the formation of a ceramic composite consisting
    only of boride phases with an artificially created hierarchical superstructure.
    Such a composite was formed during the reaction-driven consolidation process using
    a mixture of ZrB2, tantalum and amorphous boron powders. The homogeneity of the
    reaction between these powders at 1900 °C allowed the forming of a highly reproducible
    and repetitive superstructure where Ta3B4 forms a chain-like mesh which entraps
    the ZrB2, ZrB, TaB and (Zr,Ta)B2 phases. The multiboride ceramic composite exhibited
    extremely high hardness: 28.6±3.2 GPa or 22.6±0.6 GPa. These were estimated using
    98 N and 196 N loads, respectively. At 2000 °C, the multiboride composite showed
    a strength of nearly 400 MPa and fractured in an elastic manner at the loading
    rate of 2.5 mm/min. This level of strength is usually observed for the bulk zirconium
    diboride at room temperature. The main factors leading to the improvement of the
    mechanical properties were considered to be the formation of the (Zr,Ta)B2 solid
    solution as well the composite structure.'
