Abstract

A zirconium diboride (ZrB₂) based composite with silicon carbide platelet (SiC_pl) of 15% in volume was prepared by spark plasma sintering (SPS) at 1600°C for 5 min with pressure and heating rate of 30 MPa and 100°C/min, respectively. The densification behavior during sintering, mechanical properties and microstructure of the composites were investigated. Influence of preferred orientation of SiC_pl on the mechanical properties of the ZrB₂-SiC_pl composite ceramic was discussed. Results show that the SPS can decrease the sintering temperature of ZrB₂ ceramic. Microstructure of the composite with homogeneous and small grains could be obtained, indicating that the rapid sintering can inhibit the abnormal growth of ZrB₂ grains. The directional alignment of SiC_pl favors the increase of sintering and mechanical properties.
