Corrosion of β-SiAlON in Molten Aluminium, Cryolite and NaCl-KCl Mixture

Article Preview

Abstract:

β-sialons prepared from pyrophyllite resp. kaoline were used for investigation of corrosion resistance in aluminium, NaF-AlF3 and NaCl-KCl mixture. The results were compared with β-sialon of similar composition, prepared from commercial powders. The differences in corrosion process of β-sialon prepared from natural hydrosilicates and synthetic powders are discussed.
