English abstract:
A slip-casting process for the manufacturing of polysilazane-derived ceramic microparts with alumina fillers was investigated. The first aim was to produce stable powder suspensions in cyclohexane using polyvinyl pyrrolidone as dispersant. A sedimentation test was performed to characterize suspension stability. The best results could be achieved when using an ultrasonic processor for 2 h or a magnetic stirrer for 24 h.
A high accuracy in reproducing small features was obtained in a slip-casting process with self-made polydimethylsiloxane (PDMS) soft moulds and a subsequent cross-linking of the polymer at 110 °C for 72 h.
