Zirconia Brick
Zirconia brick is a type of refractory brick made primarily from zirconium dioxide (ZrO2) as the main raw material. This kind of refractory brick is known for its excellent resistance to high temperature, corrosion, and thermal shock, and is suitable for industrial applications under various extreme conditions.
PER Refractories is a professional manufacturer and supplier of zircon bricks. We have advanced equipment and production technology. We produce all kinds of zircon bricks and other refractory bricks. Such as high aluminum bricks, clay bricks, insulation bricks, magnesium bricks, fused cast bricks, and other products. Contact us for the best price.
Properties of Various Zircon Bricks
Our zircon refractory bricks are available in a range of carefully designed types, each catering to different industrial applications. Whether you are in the steel, glass, cement, or petrochemical industries, we have a zirconia brick product to suit your unique needs. Here are some common types:
Fused Cast Zircon Bricks (AZS Brick)
This refractory fire bricks are formed by melting the raw zirconia material and then casting the molten material into molds to form the bricks. They are known for their high density, low porosity, and excellent corrosion resistance.
Fused zirconia bricks are ideal for lining glass kilns and offer unrivaled resistance to the corrosive properties of molten glass. Their excellent resistance to thermal shock ensures consistent performance even under drastic temperature changes.
Zirconium Mullite Bricks
Zirconium mullite bricks combine zirconium oxide and mullite, a mineral composed of aluminum silicate, to form a brick with enhanced thermal shock resistance and mechanical strength.
These bricks are typically used in applications where slag resistance and thermal cycling properties are required, such as the construction of ladles and intermediate ladles in the steel industry.
Zirconium Corundum Bricks
These bricks are a blend of zirconia and corundum (alumina) with high refractoriness, corrosion resistance, and thermal shock resistance.
Zirconium corundum bricks are commonly used in non-ferrous industrial furnaces, cement kilns, and incinerators.
Zircon-Silica Bricks
Zirconia-silica bricks are made of zirconium oxide and silica and have good thermal insulation and resistance to corrosion by molten metals.
These bricks are used in the aluminum industry and other metal melting processes.
