Low-porosity fireclay brick is made from 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 low porosity clay brick has excellent physical properties at high temperatures and resistance to chemical erosion.

Features of Low Porosity Clay Brick

- Low porosity
- High softening point under load
- High compressive strength at room temperature
- Good volumetric stability at high temperatures and good wear resistance.
- Good anti-penetration and anti-corrosion properties.
Comparison of Low Porosity Clay Bricks and Conventional Clay Bricks
Low porosity clay brick have good stability, no sudden changes in the degree of erosion, service life in 2-3 times longer, than ordinary clay brick, and also in 2 times higher thermal conductivity and specific heat capacity, than ordinary clay brick. Heat capacity per 50% higher, than ordinary clay brick.
Delivery of low-porous clay adobe
Low porosity clay bricks are usually delivered within 7-12 days, excluding special orders.

Customers show fireclay bricks

Hi just asking if you can provide interlocking fired clay bricks (no concrete).
It Would be great if you can do it…
Looking forward to hearing from you.
I will leave my email..
It’s a challenge, but I can only challenge challengers. And I believe you can be up to it.
we will contact you as soon as possible sir
