## Description

- description: Bulk niobium diboride ceramics were consolidated by SPS at 1900C. SPS
    resulted in dense specimens with a density of 98% of the theoretical density and
    a mean grain size of 6 µm. During the SPS consolidation, the hexagonal boron
    nitride (h-BN) was formed from B2O3 on the powder particle surface and residual
    adsorbed nitrogen. The room-temperature strength of these NbB2 bulks was 420 MPa.
    The flexural strength of the NbB2 ceramics remained unchanged up to 1600 C. At
    1700 C an increase in strength to 450 MPa was observed, which was accompanied
    by the disappearance of the secondary h-BN phase. Finally, at 1800 C signs of
    plastic deformation were observed. Fractographic analysis revealed a number of
    etching pits and step-like surfaces suggestive of high-temperature deformation.
