Product Information - Sintered-MA-Spinel

Sintered spinel MgAl₂O₄ is a synthetically produced raw material available with an excess of either Al₂O₃ or MgO and used in many refractory applications.

MgO rich spinels are mainly used as alternative to magnesia chrome bricks in MgO-based refractory products, e.g. in cement rotary kilns, in order to avoid the emission of Cr_VI during the break-out of bricks, which may be dangerous for the health of the workers and the environment.
Al₂O₃ rich spinels are mainly used in Al₂O₃-based refractories, e.g. in monolithics for steel ladles, non-ferrous metallurgy and glass production.
