About this product
In recycling melting furnaces the charge composition changes with every batch, and the chemical environment the refractory meets fluctuates with it. Mullite stays stable across a wide composition range and copes well with that uncertainty. Ring bricks are produced with the wedge angle calculated from the internal diameter, so the course locks itself.
Material
Mullite is the stable crystalline phase of alumina and silica at the 3Al₂O₃·2SiO₂ composition. Because it combines creep resistance at temperature with good thermal shock behaviour, it serves both in glass furnace superstructure and in ceramic firing hardware. Alongside standard sizes, Kent Ateş Tuğla cuts fired and fused mullite blocks to the dimensions each project requires.
