Lightweight Mullite Refractory Bricks Industrial Kiln High Temperature Insulation Bricks

Our Mullite Insulation Brick is a premium quality refractory product manufactured from carefully selected high-purity clays and ceramic materials. Designed with a uniform pore structure and excellent thermal insulation properties, it provides reliable performance in applications up to 1760°C while significantly reducing energy consumption and heat storage.

• Excellent Thermal Insulation: Low thermal conductivity minimizes heat loss and improves furnace efficiency
• High Temperature Stability: Maintains structural integrity under continuous high temperature operation
• Lightweight Construction: Reduced bulk density lowers structural load and heat storage capacity
• Low Impurity Content: Minimal iron oxide and alkali components enhance corrosion resistance
• Precise Dimensional Control: Machined to close tolerances for easy installation and tight joints

• Working temperature range: 1260°C to 1760°C depending on grade
• Bulk density: 0.6-1.3 g/cm³ across different specifications
• Good compressive strength and thermal shock resistance
• Low linear shrinkage after prolonged heating
• Uniform pore structure for consistent insulation performance

• Primary hot face linings in industrial furnaces
