Properties and Microstructure of ZrB2/C Composites

doi:10.3724/SP.J.1077.2006.00946

Abstract

Abstract: ZrB₂/C composites were prepared by a hot-pressing method. The influence of dopants on the flexural strength, thermal conductivity, electrical resistivity and microstructure of these composites was investigated. Results show that the flexural strength and thermal conductivity increase with increasing ZrB₂ content up to a maximum of 131MPa and 161W/m·K at 10% addition, respectively. But the electrical resistivity reduces rapidly with increasing the concentration of ZrB₂. Correlations between the content of dopant and properties and microstructure of ZrB₂/C composites were also discussed.

Key words: ZrB2/C composites, bending strength, thermal conductivity, electrical resistivity
