Freeze-Casting of Porous Biomaterials: Structure, Properties and Opportunities
The freeze-casting of porous materials has received a great deal of attention during the past few years. This simple process, where a material suspension is simply frozen and then sublimated, provides materials with unique porous architectures, where the porosity is almost a direct replica of the frozen solvent crystals. This review focuses on the recent results on the process and the derived p...
متن کاملPreparation of aliened porous Ni-GDC nano composite by freeze-casting process
This current study reports preparation of Nickel-Gadolinium doped Ceria (Ni-GDC) composite via controlled unidirectional freeze casting of aqueous-based GDC slurry completed with nickel infiltrated into the porous GDC samples. Gadolinium doped ceria powder prepared by gel-combustion synthesis method. The oxide powder was confirmed to be the fluorite-structured of Ce0.8Gd0.2O1.9 solid solution b...
متن کاملOptimizing the Processing of Porous Melt-Derived Bioactive Glass Scaffolds
We were able to produce the first ever meltderived bioactive glass scaffold that met the requirement of an ideal bone scaffold by using the gel-cast foaming process and a new glass composition. However, initially a small fraction of sodium potassium sulfate crystals formed during processing. The purpose of this work was to study and prohibit the growth of those crystals, which was the result of...
متن کاملBiomaterials by freeze casting.
The functional requirements for synthetic tissue substitutes appear deceptively simple: they should provide a porous matrix with interconnecting porosity and surface properties that promote rapid tissue ingrowth; at the same time, they should possess sufficient stiffness, strength and toughness to prevent crushing under physiological loads until full integration and healing are reached. Despite...
متن کاملComplex-Shaped Porous Cu Bodies Fabricated by Freeze-Casting and Vacuum Sintering
Porous Cu bodies with complex shapes were fabricated by freeze-casting and vacuum sintering water-based CuO slurry. The sintered bodies showed no noticeable macroscopic defects and good shape tolerance. The interconnected pore tunnels were observed by electronic microscopy. The pore size became smaller and the porosity and volume shrinkage of sintered porous bodies decreased with the increase o...
