Ceramic properties of a refractory material are defined by its nature or reaction when exposed to heat. Refractories behave differently when exposed to heat depending on the type of the refractory and how it has been formed. For fired bricks the ceramic reactions and bonds have already been instituted by high-temperature firing.
