Description

Zirconia bricks are a type of refractory brick made of zirconia, a ceramic material with very high refractory properties. They are used in high temperature applications such as furnaces, kilns, and other industrial processes. Zirconia bricks are known for their superior strength, refractoriness and corrosion resistance compared to other Alumina Refractory Bricks.
They are mainly used in areas :

• With very high temperatures,
• Corrosion,
• Pressure and
• Mechanical shock where the normal high alumina refractory bricks cannot withstand.

Our Zircon brick ZS 65 made from stable zircon sand is a kind of great refractory brick with the zircon content over 65%. It is acid refractory with the advantages of high mechanical strength, high refractoriness under load, excellent thermal shock stability, good creep resistance and good corrosion resistance to glass liquid. It is widely used in the high erosive zones of glass furnace, chemical industry, and metallurgy industry.
