Thermodynamic Modeling and Experimental Investigation of
Shelbyville IN. One may think that refractories are primed or fired at high temperatures and can yield complex oxides of these individual components. For example mullite (3Al 2 O 3 ·2SiO 2 or Al 6 Si 2 O 13) formation occurs at firing temperatures above 1000°C in high-alumina refractories.

MulliteAn Introduction
Oct 03 2001 · A number of refractories in the steel sector have different amounts of mullite-based aggregates. Reheat furnaces steel ladles slide gates and lances are examples of mullite-aggregate-based products with different levels of alumina content. The decrease in the use of bricks has led to an increase in the use of monolithic and precast shapes.
