The Definition Between Fire Clay Brick And Lightweight Fire Clay Insulation Brick

The content of Al2O3 of fire clay brick is generally above 40%, and the Fe2O3 content is between 2.0% and 2.5%. The clinker in the furnish is 65-85%, and the content of combined clay is 35-15%. Fire clay brick is produced by mixing the pulverized bonded clay and the ground clinker, and then preparing the semi-dry mud together with the granular clinker, and firing at about 1400℃.

Fire clay insulation brick refers to light refractory products with Al2O3 between 30% and 46%,whose main principle is clay clinker or light clinker and plastic clay. It is usually produced by combustible method, or chemical method or foam method, which can be formed a porous structure.
