Bulk Density: ≧3.85g/cm2 Apparent Porosity: ≦16% Cold Crushing Strength: ≧100Mpa 0.2MPa Load Softening Start Temperature: ≧1700 Thermal Shock Stability: excellent 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:

• 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
