Syalon 050 is an advanced silicon nitride (Si3N4) ceramic offering outstanding wear, corrosion, oxidation and high temperature creep resistant properties.
Syalon 050 is a member of the Si–Al–O–N family, the first group of man-made ceramic alloys, and has been specifically designed for high performance under arduous wear conditions. Based on silicon nitride, Syalon 050 is an mixed alpha:beta-sialon advanced ceramic and has been designed to have extreme hardness and chemical and thermal stability.
Syalon 050 is a speciality material which is intended for industrial wear applications in which excellent wear, corrosion and thermal resistance are required. It also has excellent high temperature properties, maintaining good mechanical strength up to 1400°C as well as chemical stability to many molten metals and acids and alkalis.
