The mechanical properties of silicate glass-ceramics were evaluated based on the compressive strength tests. It was found that addition improved densification, refinement of the microstructure and toughening of the bodies. The maximum compressive strength of the bodies with 1 mol% Ta₂O₅ was increased 3-fold (245.92 ±0.3 MPa) in comparison to undoped glass-ceramics which was measured to be 89.04 ±0.3 MPa, while for 3 mol% it became 4-fold (387.12 ±0.4 MPa) greater. The addition of Ta₂O₅ stabilized the system by controlling the biodegradation of the glass-ceramics. It effectively depressed the apatite formation as by addition of 3 mol% Ta₂O₅ no apatite layer was observed. It may be concluded from this study that mechanical and physical properties can be improved by the addition of Ta₂O₅ , but at a cost of bioactivity. Still the optimized composition having Ta₂O₅ ≤ 1 mol% may provide appropriate strength of biomaterials for high load bearing applications.
