A bstract The addition of aluminum metal powder to fire‐clay‐grog mixtures greatly increased the strength of the fired brick as a result of an aluminothermic reaction between the metal and the silica in the clay and grog. Because the reaction takes place at 930°C. and causes the temperature to rise rapidly, it is necessary to heat these refractories only to 930°C. to produce hard, well‐fired brick. Such products have a high load‐carrying capacity at furnace temperatures and also a fair spalling resistance.
