Abstract
In a process for producing ceramic sliding bodies containing hollow chambers from a green solid parent body and a green film body containing hollow chambers, the green film body and the green solid parent body are laminated together, the organic constituents are removed by heating from the green body so obtained or the organic constituents are carbonized. Subsequently, the body is fired or siliconized. According to the invention, the green solid parent body is produced from the ceramic green material of the film body, in particular from film residues which are produced in producing the green film body containing hollow chambers. The film residues may be comminuted to form a powder in a mill.
