Preparation of (Ca plus M) (M=Mg, Yb, Sr) Co-doped alpha-SiAlON powders by combustion synthesis


In this paper, alpha-SiAlON powders co-doped with (Ca+M) (M=Mg, Yb, Sr) were prepared by combustion synthesis. The effect of Ca incorporation on the phase composition and grain morphology of reaction products was discussed. The experimental results showed that Ca incorporation promoted the growth of rod-like alpha-SiAlON crystals in (Ca+Mg) and (Ca+Yb) systems. For (Ca+Sr) system, the addition of Ca assisted Sr into alpha-SiAlON crystal lattice and increased the relative content of alpha-SiAlON in reaction product.
