High-performance Mullite Insulation Bricks For Industrial High-Temperature Applications

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.

Technical Specifications

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.

Frequently Asked Questions (FAQ)

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
