Fire Clay Bricks
Axim’s fire clay bricks possess mechanical strength and can be subjected to extreme thermal cycling and thermal shock. Fire clay bricks also have a high thermal mass which ensures they retain heat and provide excellent energy efficiency.
Fire clay bricks are made by firing a clay based composition until partly vitrified and for specialist applications can also be produced with a glazed finish. Normally fire clay bricks contain 40-50% alumina depending on the maximum operating temperatures.
High Alumina Bricks
Axim’s high alumina bricks are produced with selected bauxite chamotte as main raw material, fired at 1450-1470℃ by advanced process with strict quality control.
High alumina bricks have great features like high temperature performance, great corrosion and wear resistance, high bulk density, low iron content, etc.

The journey begins with the selection of premium raw materials. For Fire Clay Bricks, clays rich in kaolinite are chosen, while High Alumina Bricks rely on bauxite, known for its high alumina content.
These raw materials are ground into a fine powder and mixed with water to form a pliable clay. This mixture is then molded into the desired brick shape, ensuring consistency in size and form.
Once shaped, the bricks undergo a drying process to remove most of the moisture. This step is crucial to prevent cracking during the firing phase.
The transformation occurs in the kiln, where bricks are heated to temperatures between 1400°C and 1470°C. Fire Clay Bricks vitrify at lower temperatures, while High Alumina Bricks require higher temperatures to achieve their characteristic strength and stability.
Post-firing, bricks are slowly cooled to room temperature. This gradual process is essential to avoid thermal shock and potential damage. The final step involves quality checking and any necessary finishing touches before the bricks are ready for use.
This meticulously structured process, from raw material selection to the final quality check, ensures every brick meets the industry’s highest standards. With a focus on reliability and performance, these Fire Clay and High Alumina Bricks are crafted to offer unparalleled durability and efficiency in high-temperature applications.
The following are the common types of fire clay bricks you can use for your projects. Read on to see what type of projects you can apply them to:
