Magnesia-alumina Spinel Brick
When the temperature fluctuates, the expansion and contraction of magnesia-alumina spinel bricks are relatively uniform. With better thermal shock resistance, refractoriness under load and strength of magnesia-alumina spinel brick are also better than those of the magnesia bricks. In addition, the ability of magnesia-alumina spinel bricks to resist alkaline slag and iron oxide slag is stronger than that of magnesia bricks. What is more, the resistance of magnesia-aluminum spinel bricks to alkali slag and iron oxide slag is stronger than that of magnesia bricks.
