Sintering Al2O3-B4C ceramics
- 126 Downloads
Microstructural development of Al2O3-B4C composite ceramics has been studied as a function of Al2O3 and B4C powder types, and also in various sintering atmospheres. Boron carbide suppresses the sinterability of Al2O3 powder, and the densification of the composite is strongly dependent on both B4C and Al2O3 properties. Temperatures ⩾ 1700‡ C cause significant increases in sintering kinetics.
