Description

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.

As a professional zirconia bricks manufacturer, we have exported different zircon refractory bricks to more than 30 countries. Please kindly read the following more information and make Inquiry.

Scope of application
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.

Advantage

lGood slag resistance

lLow thermal expansion rate

lThermal conductivity decreases with increasing temperature

lHigh load softening temperature

lHigh abrasion resistance

lGood thermal shock resistance

lLong using life
