Is the bulk density of mullite insulating bricks 0.8 or 1.0? Did you choose the right one?

Comparison of Mullite Insulating Bricks by Bulk Density

Bricks with Bulk Density 0.8 g/cm³
Low thermal conductivity and excellent insulation performance
Lower compressive strength
Poor slag resistance – prone to slag corrosion during use
Suitable for applications where insulation is prioritized over mechanical or chemical resistance

Bricks with Bulk Density 1.0 g/cm³
Better slag resistance – more resistant to slag attack, leading to longer service life
Higher thermal conductivity – insulation performance slightly reduced
Slightly higher compressive strength
Suitable for harsher service environments where chemical resistance and durability are required

 Selection Recommendation

When selecting mullite insulating bricks, it is important to choose the appropriate bulk density based on your operating conditions and application requirements.
