AC6132 Mullite Insulation Brick

Mullite Insulating Bricks Description

Mullite insulating bricks are refractory bricks primarily made from mullite, a mineral that consists of aluminium oxide (Al₂O₃) and silicon dioxide (SiO₂) in the formula 3Al₂O₃-2SiO₂. These bricks exhibit excellent high-temperature stability, low thermal conductivity, and good thermal shock resistance, making them ideal for use in high-temperature applications where both insulation and durability are needed.

Frequently Asked Questions

Q1: What is a mullite insulating brick?

Mullite insulating bricks are refractory bricks primarily composed of mullite, a mineral made from aluminium oxide (Al₂O₃) and silicon dioxide (SiO₂). These bricks are employed due to their excellent thermal stability, low thermal conductivity, and good thermal shock resistance for high-temperature applications.

Q2: What sizes and shapes are available for mullite insulating bricks?

Mullite insulating bricks are available in various standard sizes (e.g. 230x114x65 mm) and shapes (rectangular, curved, wedge-shaped, etc.). Custom sizes and shapes can also be manufactured upon request.

Q3: How does a mullite insulating brick compare to other refractory bricks?

Mullite insulating bricks generally exhibit lower thermal conductivity and better thermal shock resistance compared to many other refractory bricks, making them suitable for applications where insulation and high-temperature performance are critical.
