Titanium porous scaffolds from precursor powders: rheological optimization of TiH2 slurries

Titanium macroporous scaffolds were prepared from TiH2 suspensions by reactive sintering, using inverse replication of a sacrificed polymer sponge. This work describes investigation on the rheological behaviour of TiH2 suspensions with a maximum solid content of 45 vol.% in water. Stabilization of the suspensions was investigated by sedimentation tests and rheology measurements and optimized by using the proper concentration of dispersant and gelling agent.
