Product Details

Zircon brick: 
锆英石砖01_.jpg

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:

Good slag resistance

Low thermal expansion rate

Thermal conductivity decreases with increasing temperature

High load softening temperature

High abrasion resistance

Good thermal shock resistance

Long using life
