Overview

This analysis demonstrates how varying the pH during hydroxyapatite synthesis from calcium nitrate affects yield and properties, suggesting optimal conditions for enhanced osteoconductivity.

Key Points

  • Submicron-sized hydroxyapatite was successfully synthesized demonstrating enhanced osteoconductivity and supporting bone formation.
  • The optimal pH for a high yield and the stoichiometric Ca/P ratio of 1.67 was determined to be 11, yielding a Ca content of 2.56% and a P content of 4.28%.
  • Synthesis was achieved using the precipitation method with calcium nitrate tetrahydrate, followed by comprehensive characterization using multiple techniques including X-Ray Diffraction and SEM.
  • Results confirmed effective synthesis of hydroxyapatite at optimal conditions, emphasizing the relationship between pH and material properties for biomedical applications.
