Fabrication of ZrB₂-Based Ceramics Doped with ZrSi₂

Abstract

With the addition of ZrSi2, the highly densified ZrB2-based ceramics were fabricated by hot pressing. The relative density increased with increasing the volume fraction of ZrSi2­and sintering temperature; the Vickers hardness increased with increasing the sintering temperature, but decreased with increasing the volume fraction of ZrSi2­.
