Magnesia Alumina Spinelsteen

Magnesia-alumina spinel brick is made of magnesia-alumina spinel ((MgAl₂O₄ abbreviated as MA)) as the matrix, using high-quality high-purity magnesia and Al₂O₃-containing ore, through batching, mengen, billet making, drogen, firing and other processes. Alkaline refractory products are known for their superior thermal shock resistance to magnesia bricks and are widely used in masonry cement rotary kilns, lime rotary kilns, open hearth furnaces, elektrische oven daken, enz.
