An evaluation of the B4C formation in sintered ZrB2-SiC ceramic composites at 2100 °C
The present study was concerned with the high temperature sintering behaviour of zirconium diboride ceramics mixed with fine silicon carbide. Zirconium diboride-silicon carbide (ZrB2-SiC) ceramic composites were pressureless sintered at 2100 °C under flowing argon environment, for a hold time of 150...
