The invention relates to a method for producing transparent ceramic objects having an RIT > 10% in the wave length range of 300nm to 4000nm and a wall thickness of 2 mm. Said method consists of the following steps: producing a slip by dispersing a ceramic powder, the particle size of which is d50 < 5µm, preferably between 5nm and 500nm; producing a granular material, the particle size of which is d50 < 1mm, preferably between 50µm and 500µm, more preferably between 80µm and 300µm, from the slip by means of fluidised bed granulation; pressing the granular material in a simple, non-cyclical manner to form a green body; sintering the green body to form a sintered body; and re-densifying the sintered body. |
