Magnesia-Chrome Bricks

Magnesia-chrome bricks are refractory products with magnesium oxide (MgO) and chromium trioxide (Cr2O3) as the main components, and periclase and spinel as the main mineral components. This type of brick has high refractory resistance, high high-temperature strength, strong resistance to alkaline slag erosion, excellent thermal stability, and certain adaptability to acidic slag. The main raw materials for manufacturing magnesia chrome bricks are sintered magnesia and chromite. The purity of magnesia raw materials should be as high as possible.
