Multi-phase ceramics by computer-controlled pressure filtration

Mattern, A.; Oberacker, R.; Hoffmann, M. J.

Abstract:
A novel apparatus for computer controlled pressure filtration has been
constructed. With it, the precise flow rate of multiple ceramic
suspensions of different compositions can be controlled. Suspensions
are mixed before entering the filtration chamber. By dynamically
adjusting the different flow rates, mixed compositions anywhere between
100% composition A to 100% composition B can be realised as a function
of the filter cake height. This is suitable for producing e.g.
functionally graded materials or layered structures. This has been
demonstrated for alumina-zirconia composites. The process is suitable
for all materials that can be handled by slip casting.
