the importance of porosity to fireclay castable
Alumina Bricks Better Than Fireclay Bricks WhyRongsheng
Aluminum oxide is the major components and is of vital importance in many fire bricks due to its high melting point. High alumina bricks and fireclay bricks can be divided based on the content of aluminum oxide Bricks with aluminum oxide contained more than 55 are high alumina bricks while those lower than 55 are fire clay bricks.

· The porosity also makes IFB more susceptible to chemical attack by gases fumes slags etc. The porosity in IFB or any other insulating refractories creates a large amount of free surface area. Since chemical attack starts at surfaces porosity leads to poor chemical resistance as compared to dense refractories of similar compositions.

Unlike fired products fireclay castables have good plasticity that is the refractory lining can release stress through its own deformation without being damaged. In the construction process of monolithic refractories it is important to consider longer heating and drying times and to use a high enough temperature to fully dehydrate the binder.
