［GENERAL INFORMATION］

CMAX high alumina firebricks are classified according to alumina content ranging from 48% to 95%, manufactured from such mineral as bauxite, corundum, etc. by mixing, press-forming, drying, sintering and machining. CMAX high alumina bricks feature stable mechanical strength and thermal shock resistance, with high refractoriness of no lower than 1750℃.

CMAX 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.
