Alkali-Resistant Brick

Description:

Alkali-resistant brick is a new type of clay or semi-silicon refractory material, which has excellent alkali resistance. At a certain temperature, the kiln gas and the alkali in the kiln material are used to condense on the brick surface and chemically react with the brick surface to form a high-viscosity glaze layer, which closes the passage of alkali to the brick body and continues to erode. Alkali resistance prevents "alkali cracking".

Advantage:

Excellent alkali corrosion resistance

Application:

Cement rotary kiln
