Syalon 110 is a composite grade of the Si-Al-O-N (sialon) family of ceramics, which is processed under carefully controlled conditions to give a material with some unique properties.

Syalon 110 was originally developed as a break ring for the horizontal continuous casting of steel. As such, its properties include improved corrosion resistance to steel compared to other Syalons, outstanding thermal shock resistance and usable up to temperatures in excess of 1450°C.
