摘要： The present invention relates to refractories with a composition gradient for lining the interior surface of combustion chambers. The invention envisages the use of refractories characterized by the presence of a number of layers with a different chemical composition to form a gradient along the cross section of the material. The presence of the composition gradient serves to combine the corrosion resistance of the surface layer, facing towards the inside of the combustion chamber, with the shock resistance of the bulk material.
