Zirconia Brick
MOQ:5 tons
Description
Zirconia bricks have the advantages of high mechanical strength, good thermal shock stability, and resistance to glass liquid corrosion. As the thermal conductivity of majority of other refractories is much higher than zirconia refractories , zirconia brick is used as a high temperature insulating refractory. Zirconia refractory is one of the main refractory materials for glass furnaces because it is not easily wetted by molten glass and has a low reaction with molten glass.
Features
High temperature resistance / High performance to large thermal expansion coefficient and wear / Good resistance of chemically aggressive /
Application
The zirconia brick uesd as the bottom paving materials for electronical and special glass tanks
Used in the key position of E glass fiber melting furnace and electric glass furnaces
Used as high corrosion resistant burner blocks
