Direct consolidation is a technique
in which a ceramic suspension transforms from a liquid state to a solid
body without any removal of water. The consolidation can be achieved by
the formation of a gel network in the water by polymerisation of a monomer
or by using polysaccharides. The ceramic particles are then immobilized in
the gel, which is an advantage of this technique as it improves the
homogeneity in the shaped component and thus also the dimensional control
during sintering. Another advantage is the fact that you can prepare more
complex-shaped components than when using other methods like pressing or
slip casting. These advantages are the reason for the industrial interest,
which includes both medical and technical applications.
The aim of the
project is to evaluate and further develop a suitable direct consolidation
method that can be used in combination with freeform-fabricated moulds.
The project will include both ceramic processing, preparation of
freeform-fabricated moulds and evaluation of the prepared materials.
