Low Cost SiAlON from Pyrophyllite with High Hardness and Good Corrosion Resistance

Abstract:

Bulk ceramic materials on the base of β-sialon were prepared from hydrosilicates. Except of some mechanical properties (HV, KIC) also the corrosion resistance of β-sialon against Cl-, iron and steel was investigated. The results were compared with β-sialon of similar composition z = 3.8, which was prepared from commercial powders Si3N4, AlN and Al2O3. The differences in mechanical properties of β-sialons prepared from natural hydrosilicates and synthetic powders are discussed.
