Effect of NH4Cl addition on the morphology of β-SiAlON powders prepared by salt-assisted nitridation

A novel method of fabricating β-SiAlON powders by salt-assisted nitridation using NaCl and NaF as the molten salt medium is proposed. The salt-assisted nitridation synthesis was carried out with Al, Si, and SiO2 powders, fixed amounts of NaCl and NaF, and varying amounts NH4Cl, which was used as an...
