PROCESS FOR PRODUCING THIN TRANSPARENT CERAMIC PARTS AND THIN TRANSPARENT CERAMIC PARTS
The invention relates to the field of ceramics and concerns a method for use in displays of electronic devices with high mechanical stress, for example. The object of the present invention is to provide a method by means of which thin ceramic parts having thicknesses of substantially <1 mm with high transparency are produced. The object is achieved by a method for producing thin transparent ceramic parts, in which ceramic powders are mixed together with a solvent and a monomer and a photoinitiator, and at least 0.0005% by mass of a photoinitiator is added, the mixture is subsequently introduced into a mould, then the mixture is irradiated for at least 1 min with light which has a wavelength for activating the photoinitiator, the moulded body is subsequently removed from the mould and dried, and then the debinding and sintering of the moulded body is carried out.
