Product Details
Zirconia Mullite Brick for Sale
Fireramo’s zirconia mullite bricks are high performance refractory materials made of high purity alumina and zirconia as the main raw materials, through scientific formula, high pressure moulding, high temperature sintering and other advanced technology. This material has a unique microstructure, with the strength and toughness of zirconia and the thermal shock resistance and stability of mullite. Fireramo supports customised zirconia mullite bricks in various shapes and sizes.
Fireramo zirconia mullite bricks features
High-quality raw materials: Fireramo zirconia mullite bricks are rich in alumina and zirconium oxide and have a high purity, which guarantees the excellent performance of the bricks, e.g. 30% zirconium oxide in the FLMZM-30 model, which gives the product excellent thermal shock resistance and abrasion resistance.
Extremely low impurities: SiO2, Fe2O3 and other impurities are strictly controlled at a low level, which effectively prevents the structural deterioration of the brick body under high temperature environment and enhances its high temperature stability.
Excellent physical properties: Fireramo zirconia mullite bricks have an apparent porosity as low as ≤17% and a high bulk density of ≥3.10g/cm³, which provides good heat insulation and heat preservation and high strength, with a cold compression strength of ≥90MPa, ensuring that the brick can still maintain a stable form under extreme working conditions.
Extremely high refractoriness: Fireramo zirconia mullite bricks have a refractoriness of more than 1630°C under a load of 0.1 Mpa, and at the same time, the permanent linear change in reheating at 1500°C is very small, only ±0.3%, which shows excellent high-temperature performance and stable dimensional accuracy.
Excellent thermal stability: the thermal expansion of Fireramo zirconia mullite bricks from 20 to 1000°C is controlled within the range of 0-0.6×10-6, and the average value of thermal conductivity at 800°C is ≤2.19W/(m-K), which shows superior thermal stability and an energy-saving effect.
Application of Fireramo zirconia mullite bricks
Fireramo zirconia mullite bricks are widely used in metallurgy, ceramics, glass, chemical industry, electric power and other high-temperature industrial fields, such as blast furnaces, hot blast furnaces, glass furnaces, ceramic furnaces and other equipment, such as high-temperature kiln linings, runners, combustion chambers and other key parts.
