AZS Brick
AZS brick is used as refractory materials for high temperature and erosion resistant kilns such as glass industrial pool kilns, glass electric kilns, slides in the steel industry, and kilns in the soda ash industry.

Description of AZS Brick
Fused bricks, also known as fused zirconia corundum bricks, are abbreviated as AZS, which are arranged in the order of their content according to the three chemical components of the Al2O3-ZrO2-SiO2 ternary system phase diagram. AZS is abbreviated from “A” of Al2O3, “Z” of ZrO2 and “S” of SiO2, according to JC/T industry standard.For example, No. 33 fused zirconia corundum refractory brick is referred to as “AZS-33#”, No. 36 fused zirconia corundum refractory brick is referred to as “AZS-36#”, and No. 41 fused cast zirconia corundum refractory brick is referred to as “AZS-41#” .
Classification and Application of AZS Bricks
AZS-33 Brick
- Al2O3: 50%
- ZrO2: 32.5%
- Volume Density: 3.75g/cm³
- Cold Crushing Strength: 200MPa
AZS-33 has good corrosion resistance to liquid glass, is not easy to produce stones or other defects, and has low possibility of producing small bubbles. Therefore, AZS-33 bricks are widely used in glass kilns, mainly applicable to the upper structure of the melting pool, the pool wall bricks and paving bricks of the working pool, and the material channel.
AZS-36 Brick
- Al2O3: 49%
- ZrO2: 35.5%
- Volume Density: 3.85g/cm³
- Cold Crushing Strength: 200MPa
In addition to having the same eutectic body as the AZS33 brick, AZS36 brick is suitable for areas with high liquid glass flow rate and high temperature, such as melting pool wall bricks, paving bricks, charging port bricks, etc., because of the increase of more interlocking zirconia crystals and the decrease of glass phase content.
AZS-41 Brick
- Al2O3: 45%
- ZrO2: 40.5%
- Volume Density: 4.00g/cm³
- Cold Crushing Strength: 200MPa
AZS41 is the most excellent product in the melting and casting AZS series, with extremely high resistance to liquid glass corrosion and extremely high glass phase seepage temperature. It is widely used in key parts such as tank wall, feeding inlet corner, flow hole, kiln ridge, tank bottom bubbling and all electric melting furnace at the hot spot of glass furnace.
