Ziel

The proposal is concerned with 4 principal lines of research:
the synthesis of polymeric, organometallic precursors with a high ceramic yield and the study of their pyrolysis and conversion to ceramic;
the direct conversion of the precursors into dense ceramic materials;
the use of precursors as an interparticulate bond as well as acting as an injection moulding binder in the fabrication of pressureless sintered silicon nitride;
the infiltration of precursors into unidirectional, 2-dimensional and 3-dimensional fibres, preforms to fabricate carbonitride bonded fibre composites.

A small pilot plant has been built to produce 5 to 6 kg of ceramic precursor per batch. A fusible solid precursor has been developed for the injection moulding phase. Dense ceramics have been successfully produced from pressed, crosslinked ceramic precursor powders. Work is underway on the fabrication of pressureless sintered silicon nitride using precursors and the injection of fabric preforms by precursors.
