Features And Applications Of Zircon Refractory Brick

Zircon brick is a high-technology material used for industrial applications because of superior mechanical, thermal, electrical, chemicaland optical p roperties. It is widely used in the high erosive zones of glass furnace, ch emical industry, and metallurgy industry.

Zircon brick is made from stable zircon sand. Zircon sand is based on zirco nium silicate (ZrO2.SiO2 or ZrSiO4).

Zircon brick is acid refractory with the advantages of high mechanical stre ngth, high refractoriness under load, excellent thermal shock stability, go od creep resistance and good corrosion resistance to glass liquid. It is re sistant to most oxides and not wetted by many metals and is therefore an ex cellent crucible refractory material in metallurgy industry.

In glass industry, Zircon brick is widely used in glass contact portion of alkali free or low-alkali glass melting furnace and the upper area of flame space and frequent thermal shock region of alkali-free or low-alkali glass , sodium-calcium glass, boron-silicate glass, lead glass and other technica l glass melting furnace. It is also suitable for paving and secondary layer of paving bottom, back lining, channel blocks, sidewall of meter of glass fiber furnace and floating glass tanks. Additionally, it can be used as neu tral brick, skew brick in soda-lime glass kiln.

It can be also used in transition region between up roof silica brick and f usion zirconia-corundum brick or fusion zirconia-mullite brick, transition region between silica brick and magnesia brick, crown, burner, thermal coup le, peep hole, secondary layer of melting bottom and back lining. In additi on, it is also applied as the ladle lining for metallurgical industry.

Sunrise Refractory offers various types of Zircon or Zirconia bricks and ot her Zircon related refractory bricks such as high dense zircon brick , fuse d cast zirconia brick,AZS brick, Fused Cast AZS Brick and Zirconia-Mullite Brick etc.
