Range
Sintered
Subtitle

Sintered high-alumina 93%

Description

High alumina content sintered material. Very good glass contact properties with the low glass defect potential.
Available in complex and large shapes.

Typical application

BPAL M is mainly used in forehearth as glass contact channel blocks to reduce glass defects such as cat scratches and stones.

Good corrosion resistance and low porosity associated with good thermal shock resistance.
