Sintering of Al2O3aSiC composite from sol-gel method with MgO, TiO2 and Y2O3 addition

Al2O3aSiC composite ceramics were prepared by pressureless sintering with and without the addition of MgO, TiO2 and Y2O3 as sintering aids. The effects of these compositional variables on final density and hardness were investigated. In the present article at first I--Al2O3 and I2-SiC nano powders h...
