SYALON 110

Slide 1

Syalon 110 is an advanced silicon nitride (Si₃N₄) based ceramic composite offering outstanding thermal shock resistance and corrosion resistance to ferrous metals.

Slide 1

Syalon 110 is a member of the Si–Al–O–N family, the first group of man-made ceramic alloys, and was specifically developed for use as a break ring in the horizontal continuous casting of steel. As such, it's properties include improved corrosion resistance to molten steel over other silicon nitride ceramics, as well as outstanding thermal shock resistance and is usable up to temperatures in excess of 1450°C.

The table below lists typical thermomechanical and electrical properties for Syalon 110.
