Factory Wholesale JM 23 JM 26 B1 B2 Low Density 0.8g/cm³ Mullite Insulation Brick for Industry Kiln

Leadsun Refractory supplies several grades of insulating brick for use in applications from 900℃ to 1760℃. Each grade of brick is formulated to meet specific thermal and physical requirements. After firing, each brick is machined to close dimensional tolerances.

Overall, mullite insulating bricks offer a reliable, efficient, and durable solution for applications requiring thermal insulation, structural stability, and energy conservation under demanding operating conditions.

Insulating bricks are manufactured utilizing exceptionally high purity clays or mullite or other ceramic materials. The carefully graded organics used during the manufacturing process burn out during firing to give a uniform pore structure.

Key Advantages

Strong compressive strength: Enables them to withstand significant structural loads and mechanical stress at elevated temperatures without deformation or failure.
High insulating properties: Low thermal conductivity effectively minimizes heat transfer and ensures excellent thermal efficiency in furnaces, kilns, and other thermal equipment.
Low heat storage capacity: Allows for rapid heating and cooling cycles, reducing energy consumption during thermal cycling and improving overall process efficiency.
Energy saving: Inherent energy-saving capability stems from reduced heat loss, lower fuel consumption, and improved thermal management in industrial heating systems.
High purity: Primarily composed of mullite (3Al₂O₃*2SiO₂) phases, ensuring superior chemical stability and resistance to corrosion from alkalis, acids, and other aggressive atmospheres.
Tight dimensional tolerance: Ensures precise installation, uniform lining, and minimal joint gaps, which further enhances thermal insulation and structural integrity.
Low impurities: Minimizes unwanted reactions, contamination risks, and degradation in high-temperature environments, thereby extending service life and maintaining consistent performance.

Applications

Primary hot face linings
Hot blast stoves
Back-up insulation for furnaces and kilns
Sulphur recovery equipment
Flue insulation
