Magnesia zirconia bricks are made of high-purity fused magnesia and synthetic magnesia-zirconium sand as raw materials. After high-pressure molding and high-temperature firing, they have excellent corrosion resistance to alkali metals, oxides and sulfides. Magnesia zirconia bricks Features: 1.Excellent corrosion resistance. 2.High strength. 3.Good stability. 4.Good slag resistance. 
 
Dimensions of Magnesia Zirconia Brick: The standard size of it is 230*114*65mm; and 230*114*76mm, 230*114*32mm, etc are also common used. Except for the common sizes, some special shapes could be customized according to the customers' requirements
