Cordierite Bricks

Cordierite Bricks

The basic raw materals for cordierite products are cordierite fireclay and special MgO-substrates which contribute to the cordierite formation at the point of an Al₂O₃ and SiO₂ surplus, in particular in the bonding matrix. Usually shaping is done by hydraulic dry pressing, in particular for the manufacture of large shaped kiln furnace covers.

Cordierte rich products are characterized by their excellent thermal shock resistance due to their very low reversible heat expansion. Their main area of use in kiln cars and as kiln furniture for ceramic firing furnaces relies on the latter.
