ABSTRACT

Science recent time different processing methods are in use to structure ceramic green tapes. These processes mostly need completely dry green tapes and long process times for generating structures. One new aspect is the structuring of ceramic slurries during casting by using binder systems, which polymerize under ultra violet radiation.

This paper concerns with the development of new processing routes for structuring ceramic green tapes. Therefore a ceramic powder was dispersed mechanically into commercial available UV-curable binders. The final slurry was rheologically investigated and cast by using the doctor-blade method. Also measurements of the maximum achievable curing thickness for one slurry composition have been made. First casting trials have been carried out by applying the slurry onto a plane polyester carrier tape, which was well processed with doctor blade method. Results of polished cross sections are presented. For the direct structuring different structured carrier substrates, for example structured silicone moulds and structured papers have been used. They allow a high through put production of structured ceramic green tapes with a wide range of possible structures and a direct subsequent treatment.
