Fused and sintered magnesite alumina spinel are refractory materials made from bauxite, magnesium oxide, and alumina. They have strong resistance to thermal shock and slag corrosion, making them suitable for nozzle bricks, ladle castables, induction furnace linings, and magnesite alumina spinel bricks. Sintered magnesite alumina spinel uses high purity alumina and magnesia, and is sintered at high temperatures, giving it low impurities and a homogeneous structure that make it well-suited for basic refractories and high-quality ladle and continuous casting slide plate castables.
