Synthesis and characterization of alkaline earth and rare earth doped sialon Ceramics by spark plasma sintering
Several sialon ceramics compositions were synthesized by selecting metal oxides (MOs) in
the nanosize range as additives in the oxynitride network. Nanosized precursors, including
Si 3 N 4, SiO 2, AlN, Al 2 O 3, and MO (MO= MgO, CaO, SrO, BaO, Y 2 O 3, La 2 O 3, CeO 2,
Nd 2 O 3, Eu 2 O 3, Dy 2 O 3, Er 2 O 3 and Yb 2 O 3,) were used in the present study. Probe
sonication and spark plasma sintering techniques were used for mixing the powder
precursors and subsequent synthesis of sialon ceramics at a relatively low temperature of …
