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:

l 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:

l Good slag resistance

l Low thermal expansion rate

l Thermal conductivity decreases with increasing temperature

l High load softening temperature

l High abrasion resistance

l Good thermal shock resistance

l Long using life
