Low Porosity Fire Clay Brick

Low-porosity fire clay brick is made of low-aluminum mullite as the main raw material, which is formed by high-pressure molding and high-temperature sintering. The main mineral composition is the mullite phase, and the low-porosity clay brick has excellent high-temperature physical properties and chemical erosion resistance.

Features of low porosity clay bricks

1. Low porosity
2. High softening temperature under load
3. High compressive strength at room temperature
4. Good volume stability at high temperatures and good wear resistance
5. Good anti-penetration and anti-corrosion properties

Comparison of low porosity clay bricks and ordinary clay bricks

Low-porosity clay bricks have good stability, no sudden change in the degree of erosion, 2-3 times longer life than ordinary clay bricks, a 2 times higher thermal conductivity and specific heat capacity than ordinary clay bricks. The heat storage capacity is 50% higher than ordinary clay bricks.

Shipping of low-porosity clay bricks

Low-porosity clay bricks can generally be shipped within 7-12 days, except for special orders.
