Green chemical synthesis of calcium phosphate bioceramics.

A standard preparation technique of the graft relevant calcium phosphates (which includes the dissolution of watersoluble compounds containing calcium cations and phosphate anions, the slow addition of one solution into another under alkaline pH, followed by aging, suspension separation, washing off, drying and sintering at elevated temperatures) has been reconsidered from an environmental point of view. The entire process has been simplified to a single stage, and a number of intermediate stages have been excluded without influencing the quality of the final products. In this report, we launch a new environmentally friendly preparation technique of calcium phosphate bioceramics for potential use as bone grafts.
