High alumina bricks are premium quality refractory bricks that can withstand high temperatures, stresses, abrasions, and corrosion in industrial furnaces. The production of these bricks involves the use of aluminum oxide content raw materials and controlled firing processes to form a dense and durable structure. Based on usage, these bricks are classified into various alumina brick grades like 40% alumina brick, 50% alumina brick, 60% alumina brick, and 70% fire brick.
