High alumina firebricks are classified according to the alumina content which is from lowest 48% to highest 95%, manufactured from mineral of bauxite, corundum, etc. By mixing, press-forming, drying, sintering and machining. High alumina bricks feature stable mechanical strength and thermal shock resistance, with high refractoriness of no lower than 1880¡æ, high alumina bricks are commonly used as refractory lining exposed to heat directly or backup insulation linings in various types of industrial kiln or laboratory furnace.
