Product Introduction
AZS brick, the full name is fused zirconium corundum brick (abbreviated as AZS in English), is a high-performance refractory material with alumina (Al₂O₃), zirconium oxide (ZrO₂) and silicon dioxide (SiO₂) as the main components.
The naming of AZS bricks is based on the content of Al₂O₃, ZrO₂, and SiO₂, which are represented by A, Z, and S respectively. For example, AZS-33# means ZrO₂ about 33%, AZS#36 means ZrO₂ about 36%, and AZS#41 means ZrO₂ about 41%.
