The fused zircon corundum brick is a white solid formed by pure alumina powder and zircon sand containing zirconia of 65% and about 34% of silica in the electric melting furnace and then injected into the mold to be cooled.

Zircon brick / Zirconia bricks have the advantage of mechanical strength, excellent stability to thermal shock, resistance to
corrosion, high refractorines
s under load and inertness, high density, etc. It is widely used in glass furnace, non-ferrous metal smelting furnace, and pure steel furnace. Please see listed applications on lower right of this page.
TK BRICKS can produce serious fused cast 33#,36#,41#AZS block for glass furnace.

We can produce common shaped and irregular shaped refractory brick.And we can adjust our specifications for your application.
