Al2O3: ≥48%;
Fe2O3: ≤2.0%;
Bulk Density: ≤0.8-1.2g/cm³;
Cold Crushing Strength: 1.2-4.5MPa;
Permanent Linear Change: -2-1.0% T/ºC*12h.
Size: 230*114*65mm (standard)/other sizes;
High refractoriness: The refractoriness of high alumina insulation bricks is generally between 1580 and 1750°C. The refractoriness is higher than that of other insulating brick. This makes them suitable for use in high temperature environments.
Good thermal insulation performance: The thermal conductivity of high alumina insulation bricks is between 0.2 and 0.55 W/(m·K). The thermal conductivity is lower than that of clay insulation bricks and silica insulation bricks. This means that they have excellent thermal insulation properties.
Light weight
The density of alumina insulation bricks is between 0.5 and 1.2 g/cm³. This makes them lightweight and easy to handle. It improves construction quality.
High strength
The compressive strength of high alumina insulation bricks is between 1.0 and 2.0 MPa. This makes them strong and durable, with a long service life in high temperature mechanical applications.
Good chemical stability
Alumina has good chemical stability. This feature helps to resist corrosion from acidic and alkaline slags.

Raw Material Selection: High-purity alumina is mixed with other refractory materials, such as silica or clay, to achieve the desired properties.
Forming: The mixture is shaped into bricks using molds or extrusion techniques.
Drying: The formed bricks are dried to remove moisture, which helps prevent cracking during firing.
Firing: The bricks are fired at high temperatures (typically between 1400°C and 1600°C) to achieve their final strength and thermal properties.
Raw Materials of High Alumina Insulation Brick
Alumina
Calcined, sintered, tabular, fused, etc
Mullite
