Sintered MA Spinel is a technical ceramic material characterized by high hardness, excellent wear resistance and temperature resistance. It is a sintered material produced by heating magnesium aluminate powder at extremely high temperatures. Sintered MA Spinel is widely used in industry for applications with high thermal loads, such as crucibles, nozzles, combustion chambers and high-temperature furnaces. It is also suitable for the production of wear-resistant components and insulators in extreme environments due to its excellent properties at high temperatures and under abrasive conditions.

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 CrVI 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.
