Tailored mechanical properties of silicon nitride-hydroxyapatite composite scaffolds for biomedical applications
Original language description
Silicon nitride (Si3N4)-hydroxyapatite (HA) composite scaffolds for bone replacement were developed via pressure infiltration of HA into a porous Si3N4 matrix. The effect of replication processing parameters (SiO2 content, number of infiltrations, and calcination temperature) on the structure and mechanical properties of the porous Si3N4 matrix was investigated and compared to human trabecular bone. All fabricated Si3N4 matrices exhibited interconnected porosity comparable to trabecular bone. A matrix processed with double infiltration with 15 wt.% SiO2 suspension, followed by calcination at 1100 degrees C, demonstrated the highest compressive strength. Subsequent pressure infiltration with HA significantly enhanced both the compressive (similar to twofold) and tensile strength (> quadruple) of this matrix, yielding a composite scaffold with a compressive strength similar to that of human trabecular bone, while maintaining comparable microporosity.
