Material and Technique
Zirconia corundum mullite refractory bricks(AZS bricks) are mainly for glass furnace. use special grade bauxite and zirconite concentrate as the raw materials, are produced by reaction bonded process, introducing ZrO2 into mullite matrix, are high grade refractories.Specifications
