Bioactive calcium phosphate (CP) scaffolds have emerged as synthetic alternatives to bone graft, acting to target fracture healing and bone disease such as osteoporosis. Previous research has shown that these bioceramic materials due to their osteoinductive and biocompatible properties can potentially induce bone formation from the surrounding native tissue. Sintering temperature of CP scaffolds has been shown to influence the microstructure and properties; however, a comprehensive study to determine the influence of sintering temperature on CP scaffolds has yet to be performed. Thus, the objective of this work was to determine the microstructural properties of an injection molded CP scaffold based on the crystallographic phases and grain arrangement for different sintering temperatures. The CP scaffolds were fabricated using tricalcium phosphate and sintered at three target temperatures. The microstructural properties were characterized by different techniques such as: X-ray diffraction, scanning electron microscopy with associated energy dispersive X-ray spectroscopy, and microhardness.
