China refractory manufacturer factory price Zirconia corundum zirconia mullite Antistripping Brick for Glass melting Kiln
Zirconia bricks are made of zirconia as the main raw material, added with binders and additives, equipped in proportion, and fired at a high temperature after mixing, mixing, molding, and drying. The zirconia bricks are divided into production processes and physical and chemical indicators. It is a high-density type and a dense type.
Zirconia (ZrO2) raw material characteristics: generally good crystal shape, square short column, a few are long columnar crystals, bipyramidal crystals, there are also simple columnar and complex columnar and irregular granular shapes, etc., the color is white, light yellow , Yellow, pink, mostly white and transparent.
Zirconia bricks containing 67.23% zirconium oxide and 32.77% silicon oxide. The tetragonal crystal system, usually in the shape of a square column. The Mohs hardness is 7.5, and the expansion coefficient at 20~1000℃ is 4.2×10-6/℃. The melting point is 2430°C. The bulk density is 3.60~4.3g/cm3. The apparent porosity is 0%~18%. Load softening temperature>1550℃. It is prepared by semi-dry pressing and calcination at 1600°C.

Features of zirconia bricks:
(1) High temperature resistance, high strength and wear resistance
(2) Strong slag resistance, especially acidic slag.
(3) The thermal expansion rate is small, and the volume is stable
at high temperature.
(4) Thermal conductivity decreases with increasing temperature
(5) Excellent thermal shock resistance.
(6) High bulk density and low porosity.
(7) Corrosion resistant to molten steel and glass solution.
(8) There are standard sizes and special-shaped sizes (can be
processed by drawings)

In the application of the glass tank furnace, it is mainly used in the glass furnace slag, the fire hole, the detection hole, the breast wall of the melting part, and the sealing layer at the bottom of the arch foot pool. Zirconia bricks have good corrosion resistance to alkali-free glass, and can be used as refractory materials in contact with alkali-free glass at low temperature. Aggregate zircon bricks with good thermal shock resistance can be used for superstructures with little temperature change. In addition, zirconium corundum bricks have obvious electrical insulation properties below 1650°C and can also be used as electrode materials.
