Zirconia Corundum Brick Introduction

AZS bricks, also known as fused zirconia corundum bricks, are made by carefully selected zircon sand and industrial aluminum oxide powder in a 1:1 ratio, with a small amount of flux added, mixed evenly, melted at 1800~1900 ℃, and then cast into shape. Generally, zirconium corundum bricks can be divided into several grades according to the content of ZrO2, such as three grades of AZS-33, AZS-36 and AZS-41. They have high melting point, good chemical stability, and strong corrosion resistance to acid and alkaline media, especially molten glass.

Zirconia Corundum Brick Feature

1.Casted by melting raw material in the mold, then cooling and solidification.

2.Strong glass corrosion resistance and high thermal shock stability.

3.Good wear-resistance,slag-resistance and alkali corrosion resistance.

4.High-purity raw material, barely no pollution.

5.Top quality, long service time.

Shapes and sizes: there are great variety of formats and shapes which are available for different forming and special machine processes.

Applications of AZS Brick

1.Sodium silicate furnace, ceramic frit furnace, glass furnace, etc..

2.Important parts of furnaces where chemical erosion is serious and temperature changes frequently.

3.Lining of glass furnace.

4.The chemical industrial, metallurgical furnaces.
