Subtitle

End-cast electrofused Alumina-Zirconia-Silica (AZS) with 37% zirconia

Description

High corrosion resistance Alumina-Zirconia-Silica (AZS) for simple rectangular shapes. The very reduced casting cavity and high zirconia content increase resistance to corrosion.

Typical application

The end-cast electrofused Alumina-Zirconia-Silica (AZS) with 37% zirconia, ER 1699 RS solution is specifically designed for melting sidewall applications in flame furnaces.
