AL 100


Sintered high-alumina 99%


Highest alumina content sintered material. Remarkable resistance to vapours corrosion. Available in standard brick format.

Typical application

AL 100 is dedicated to superstructure application of reinforcement and textile fiber glass furnaces, specifically for oxy firing technology.

Highly resistant to vapour environment with its high alumina content and extremely low level of silica. Used in applications requiring good chemical and dimensional stability.

If mortar is required, use AL 100S MORTAR.
