Abstract The effect sintering additives comprising AlN and Re 2 O 3 (Re = Sc, Lu, Yb, Er and Y) in a 2:3 molar ratio on the high-temperature strength of liquid phase-sintered and subsequently annealed SiC ceramics was investigated. Clean SiC–SiC boundaries and clean SiC-junction phase boundaries without the amorphous inter-granular phase (IGP) were observed in Sc 2 O 3 -, Lu 2 O 3 - and Yb 2 O 3 -doped SiC ceramics. Clean SiC–SiC boundaries and SiC-junction phase boundaries with the amorphous… CONTINUE READING
