| 摘要 |
The invention relates to a tile with a ceramic body, it having at least two layers (1, 2) of different apparent density and the structure of the layer (2) corresponding to a conventional body structure layer and the layer (1) being interspersed with macropores. The invention relates, furthermore, to a process for producing the tile, a ceramic mass, mixed with pore-forming agent, being introduced layer by layer into a mould, slightly pressed if appropriate, and the layer of the dense ceramic mass subsequently being applied and subsequently ceramically fired in the usual way. <IMAGE>
