METHOD FOR PRODUCING TRANSPARENT CERAMIC OBJECTS BY MEANS OF FLUIDISED BED GRANULATION

A method for producing transparent ceramic objects having an RIT>10% in the wave length range of 300 nm to 4000 nm 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<5 μm, preferably betw...

Summary:A method for producing transparent ceramic objects having an RIT>10% in the wave length range of 300 nm to 4000 nm 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<5 μm, preferably between 5 nm and 500 nm; producing a granular material, the particle size of which is d50<1 mm, preferably between 50 μm and 500 μm, more preferably between 80 μm and 300 μm, 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.
