| Abstract: |
| In this study, synthesis of nano sized Al2O3.Y2O3 (YAlO3) powder was concerned as a good sintering additive for sintering of non-oxide ceramics. The synthesis method was sol-gel combustion and the starting materials were metal nitrates as oxidants and glycine as a fuel. Taguchi experimental design was used to obtain the optimum conditions of gaining nano sized Al2O3.Y2O3 powder. The studied parameters were concentration, pH, and the ratio of fuel to oxidant. The prepared nano powders were characterized by XRD and FESEM analyses. The XRD analysis proved the formation of YAlO3 and the other results demonstrated the optimum conditions of synthesis of YAlO3 nano powder. |
