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.

Graphical abstractTitanium powder scaffolds can be produced from TiH2 slurry by replication sponge reactive sintering method. This method uses a slurry with high solids loading and favorable rheological properties where the sponge is immersed.Figure optionsDownload full-size imageDownload as PowerPoint slide
