  • MgAl2O4 spinel refractory as containment liner for high-temperature alkali salt containing environments
    Patent number: 7438004
    Abstract: A method includes containing a high-temperature alkali salt containing environment using a refractory containment liner containing MgAl2O4 spinel. A method, includes forming a refractory brick containing MgAl2O4 spinel having an exterior chill zone defined by substantially columnar crystallization and an interior zone defined by substantially equiaxed crystallization; and removing at least a portion of the exterior chill zone from the refractory brick containing MgAl2O4 spinel by scalping the refractory brick containing MgAl2O4 spinel to define at least one outer surface having an area of substantially equiaxed crystallization. A product of manufacture includes a refractory brick containing MgAl2O4 spinel including an interior zone defined by substantially equiaxed crystallization; and at least one outer surface having an area of substantially equiaxed crystallization.
