Abstract

The invention relates to a ceramic surface in a casting tool, particularly a surface located outside the contouring region, which is exposed to a liquid or free-flowing aluminum material, wherein on at least one ceramic surface a layer is present consisting of an infiltration layer, diffused into the ceramic surface, structural parts in the form of Al2O3 and/or SiO2 and/or ZrO2 and/or TiO2 and a polymer of one or more polymerized phosphates and at least in sections enclosing the primary parts, the structural parts, and the sliding parts. Moreover, the invention relates to a parting agent and a method for preparing a layer of this type.
