Preparation, sintering and fracture behavior of Al2O3/LaAl11O18 ceramic composites

Al2O3/25 vol% LaAl11O18 composites were prepared by pressureless sintering at 1550°C with composite powders obtained by copercipiated method using La(NO3) · 6H2O and Al(NO3)3 · 9H2O as starting materials. The enhanced reactive activity of Al2O3 and chemically homogeneous mixing of the constituents m...
