Synthesis and properties of bone cement materials in the calcium phosphate–calcium sulfate system
- 37 Downloads
We have studied the influence of the cement liquid composition and the relationship between the components of the calcium sulfate–precipitated calcium phosphate system in a wide concentration range on the setting time, phase composition, microstructure, and mechanical properties of cement materials. The results demonstrate that the greatest promise is held by a magnesium phosphate-based cement liquid which, when mixed with powder, forms a high-strength phase, leading to a considerable increase in the strength of the cements. The addition of 20 wt % calcium sulfate to the starting mixture ensures dispersion hardening of the cements. We have obtained new cement materials offering a strength of up to 60 MPa, which are expected to find medical applications.
