Magnesia chrome brick is a type of refractory brick made by combining magnesia and chrome oxide. Magnesia chrome bricks are used in high-temperature applications that require excellent resistance to corrosion, such as steelmaking, cement production, and glassmaking. They are also used in incinerators and other high-temperature equipment used for waste disposal.

Magnesia chrome brick is commonly used in the construction of refractory linings in steel-making furnaces, such as AOD (argon oxygen decarburization) and VOD (vacuum oxygen decarburization) furnaces, as well as in cement rotary kilns, glass tanks, and non-ferrous metal smelting furnaces.
It is also used in other high-temperature industrial applications where a high level of corrosion resistance is required.
