Fused Cast AZS Brick is also called electro Zircon corundum brick, which is abbreviated as AZS because it contains Al2O3－ZrO2－SiO2. Acording to the different content of Zirconia from 33%-41%, fused cast AZS blocks can be divided into three types AZS—33#,AZS—36# and AZS—41#.

What's Fused Cast ?
The term Fused Cast refers to a manufacturing process in which the ceramic bonding is
obtained by the solidification of a mixture which has been melted in an electric furnace and
cast in liquid state into molds.
What does AZS mean?
Fused Cast AZS Brick is also called electro Zircon corundum brick, which is abbreviated as
AZS because it contains Al2O3－ZrO2－SiO2. Acording to the different content of Zirconia
from 33%-41%, fused cast AZS blocks can be divided into three types AZS—33#,AZS—36#
and AZS—41#. Fused cast AZS block is made from pure alumina powder and Zircon sand
(composed of 65% zirconia and 34% SiO2). After Alumina powder and zircon sand melting in
electric furnace, they are cast into various molds and cool themselves down to become white
solid.
Where is Fused cast AZS used?
Fused cast AZS refractory materials are among the best, thus being widely used in the
structure of glass melting furnaces. And different types are used in different parts of glass
melting furnaces as each type of fused cast AZS has a different corrosion resistance. To give
you only one example, the fused cast AZS refractory class containing 36% ZrO2 has an
excellent resistance to corrosion. This makes it a very good choice for the glass contact parts
of the melters. It is also very effective in paving blocks and side walls. The 17% ZrO2 Super
Low Exudation is very good because it allows eliminating the vitreous phase exudation. The
result is a higher quality of the glass.
As you can see, each class of materials has its characteristics that make it better for certain
processes and terrible for others. Only a team of skilled technicians can thoroughly assess all
parameters and recommend the perfect solution for each process.
