Abstract

Cement materials in the calcium phosphate–calcium sulfate system were proposed for bone tissue reconstruction. Mixtures of calcium sulfate and amorphous calcium sulfate in the weight ratios 20: 80, 40: 60, 60: 40, and 80: 20 were used as a cement flour, and an acidic solution of orthophosphoric acid was used as a setting liquid. Cement materials based on dicalcium phosphate dihydrate and calcium sulfate were obtained, and the phase composition, setting time, compressive strength, and microstructure of cements were studied. A phenomenon of dispersion strengthening of cements by adding 20 wt % calcium sulfate was detected. The obtained cement stone had a strength to 60 MPa, a setting time of 6–7 min, and uniform microstructure with a crystal size of 1–2 μm.
