Abstract

ZrB₂-10SiC, ZrB₂-20SiC and ZrB₂-30SiC ceramics were fabricated by hot pressing. The typical effects of volume fraction of SiC on the electrical properties were investigated. The electrical resistivities of as-prepared ZrB₂-SiC ceramics increased as the volume fraction of SiC increased. The room temperature electrical resistivity values for ZrB₂-10SiC, ZrB₂-20SiC and ZrB ₂-30SiC ceramics were 6.54, 8.65 and 11.29 μΩ cm, respectively. ZrB₂ acted as an electrical conductor and SiC acted as an electrical insulator in the ZrB₂-SiC ceramics. The microstructure of ZrB₂-SiC ceramics was also analyzed, which further proved the electrical resistivity measurement results.
