Alkali‐free processing of advanced open‐celled sinter‐crystallized glass‐ceramics

The cooling of a melt corresponding to the eutectic between wollastonite (CaSiO3) and diopside (CaMgSi2O6) determines synthesis an interesting example alkali-free bioactive glass, easily converted into glass-ceramics featuring two silicate phases, coupled also with åkermanite (Ca2MgSi2O7), by sinter-crystallization fine glass powders at 1000°C. fabrication scaffolds digital light processing suspended in photo-curable, sacrificial binder, is well-established technique; present paper aims disclosing novel approaches, concerning topology scaffolds, offering components remarkable strength, especially bending conditions. As alternative, glass-ceramic foams were fabricated firing porous precursors derived from gelation suspensions basic aqueous solution.
