Bioactive glass-ceramic scaffolds from novel 'inorganic gel casting' and sinter-crystallization [PDF]

, 2017
Highly porous wollastonite-diopside glass-ceramics have been successfully obtained by a new gel-casting technique. The gelation of an aqueous slurry of glass powders was not achieved according to the polymerization of an organic monomer, but as the ...
