What are the Performance Characteristics of Mullite Insulation Bricks?
Mullite insulation bricks are high-alumina refractory materials with mullite (3Al₂O₃·2SiO₂) as the primary crystalline phase. Their alumina (Al₂O₃) content typically ranges from 65% to 75%, resulting in excellent high-temperature resistance and thermal insulation properties. They are available in three different bulk densities: 0.8 g/cm³, 1.0 g/cm³, and 1.2 g/cm³, suited to varying temperatures and operating conditions. Mullite Insulation Bricks Characteristics of Mullite Insulation Bricks Excellent Thermal Insulation: Mullite insulation bricks have low thermal conductivity, effectively reducing heat loss, improving kiln insulation , and reducing energy consumption. Low heat capacity, energy-saving and high efficiency. Due to its low thermal conductivity, this material stores less heat energy, making it particularly suitable for intermittent kilns (such as shuttle kilns), significantly reducing heating energy consumption and improving thermal efficiency.
