1. The Main Characters for AZS refractory bricks：
The main raw materials for AZS bricks is industrial alumina, low quality ZrO2 and zircon sand; the auxiliary raw material is soda and borax. Then fused these raw material by three phrases arc, after process of casting, anneal, machining and inspecting, the finished products are made. These kinds of bricks have good corrosion resistance to melting glass
2. Applications：Glass kiln
3. Physical and chemical index of AZS refractory bricks for glass kiln
