Common ion effect on some calcium phosphate cements

Four calcium phosphate cements were selected to investigate whether the use of aqueous solutions of CaCl 2, Na 2HPO 4 or NaH 2PO 4.2H 2O instead of water had any effect on their properties. One cement was sensitive for the CaCl 2 solution, two others for the phosphate solutions, and the fourth cemen...

Description
Summary:Four calcium phosphate cements were selected to investigate whether the use of aqueous solutions of CaCl 2, Na 2HPO 4 or NaH 2PO 4.2H 2O instead of water had any effect on their properties. One cement was sensitive for the CaCl 2 solution, two others for the phosphate solutions, and the fourth cement was insensitive to all three solutions. The setting times were reduced considerably. However, the strength values after soaking the cements in Ringer's solution for 1 day at 37°C decreased with the use of an accelerator. The use of phosphate solutions changed the pH of the cement slurry slightly during setting, whereas the CaCl 2 solution had no effect on the pH.
