Characterization and evaluation of copper-doped akermanite ceramic

The aim of this study is to investigate the influence of copper (Cu2+) on structural and mechanical properties of akermanite ceramic synthesized via high-energy wet planetary ball-milling route. Based on structural analysis, partial substitution of copper ions did not affect the phase stability of host akermanite. Moreover, Cu2+ suppressed the grain growth, thus considerably improved the sinterability and mechanical properties of akermanite ceramic. Vickers microhardness values of doped samples increased to five- or six-times compared to that of pure akermanite at 1200°C. Our study indicated that the Cu2+-doped akermanite ceramic could potentially be used as an alternative material for bone replacement in biomedical applications.
