Mullite iInsulation bricks are a specialized type of high-alumina refractory material designed for applications requiring excellent thermal insulation and high-temperature resistance. Characterized by mullite (3Al₂O₃·2SiO₂) as their primary crystalline phase, these lightweight bricks offer a unique combination of properties that make them indispensable in modern high-temperature industrial processes.
The alumina (Al₂O₃) content in mullite insulating bricks typically ranges from 40% to 80%, with the mullite content increasing in proportion to the alumina level. Pure mullite has a theoretical composition of approximately 71.8% Al₂O₃ and 28.2% SiO₂ and a melting point of 1850°C. Varieties with lower alumina content may contain small amounts of glassy phase and other impurities, whereas high-purity varieties enhance high-temperature performance by minimizing iron oxide and alkali metal content.
| Category | Key Performance Characteristics |
|---|---|
| Low Thermal Conductivity | Ranging from 0.17 to 0.55 W/m·K depending on temperature and density, these bricks provide excellent insulation, reducing heat loss and energy consumption |
| High Refractoriness | Classification temperatures extend from 1260°C to 1760°C, with maximum service temperatures up to 1730°C |
| Low Heat Storage Capacity | The lightweight nature of these bricks reduces thermal mass, enabling faster heating and cooling cycles with significant energy savings |
| Standard Compliance | ASTM, ISO, and EN international refractory safety standards. |
Q1: What is the minimum order quantity (MOQ)?
A:There is no strict MOQ for trial orders. We can provide samples and recommendations based on your needs.
Q2: How do I choose the right grade?
A: The right grade depends on your furnace's maximum operating temperature, the atmosphere inside the kiln, and the required strength and insulation level. For example, if your furnace runs at 1500°C, you would select a grade rated for at least 1550°C (like JM-28) to provide a safety margin
Q3: Can you provide customized shapes?
A: Yes, we are often accept custom orders. we can produce the bricks in special shapes and sizes to meet the specific design requirements of your kiln or furnace
