Zircon Brick Manufacturer & Supplier

Product Description

Description of Zircon Brick

Zircon refractory brick is made of natural zircon sand (ZrSiO2) as raw material. The zircon silicate brick is fired in 1600℃ furnace with the zircon content more than 65%. The Zircon bricks have compact crystal structure, high density and high mechanical strength. Since it has good thermal shock stability, low re-fire shrinkage and high temperature creep, and has extremely high chemical stability and resistance to alkaline media, it is widely used in glass industry.

Characteristics of Zircon Brick

Good slag resistance
Long using life
Low thermal expansion rate
High load softening temperature
High abrasion resistance
Good thermal shock resistance
Thermal conductivity decreases with increasing temperature

Application of Zircon Brick

Zircon Silicate bricks is widely used in Lining of alkali-free or low-alkali glass, sodium-calcium glass, boron-silicate glass, ceramic glass,lead glass, and other technical glass melting furnace.
