Abstract: The invention relates to a ceramic moulded body, namely a roof tile, a brick, a clinker or a facade wall, consisting of an oxide ceramic base material and comprising a surface which self-cleans by means of water-sprinkling or percolation. Said moulded body has a porous, oxide ceramic coating which is photocatalytically active and has a specific surface of between approximately 25 m2/g and approximately 200 m2/g, preferably between approximately 40 m2/g and approximately 150 m2/g. The invention also, relates to a method for producing one such ordinary ceramic moulded body.
