Abstract

Calcium Phosphate ceramics are widely recognized as promising candidates for bone substitute materials due to their excellent biocompatibility, bioactivity, and osteoconductive properties. This study investigates the fabrication of interconnected porous hydroxyapatite (HA) ceramics via the direct foaming method, focusing on the optimization of synthesis parameters and the evaluation of mechanical performance using the Hertzian indentation method. By systematically varying the solid content, the microstructural and mechanical properties of the resulting ceramics were tailored to achieve an optimal balance between porosity and strength. Comprehensive microstructural analysis using scanning electron microscopy (SEM) confirmed the formation of highly interconnected porous networks. Mechanical testing validated the structural integrity of the foamed HA ceramics, demonstrating their potential for load-bearing applications in bone tissue engineering. This study provides critical insights into the direct foaming process, highlighting its potential for scalable and reproducible fabrication of porous HA scaffolds.
