Abstract

This paper describes a comparative investigation into the in vitro solubility of the calcium polyphosphates, γ-Ca(PO3)2 and β-Ca(PO3)2. The differing arrangement of their polyphosphates chains appears to result in significant dissolution of γ-Ca(PO3)2 polymorph over the β-Ca(PO3)2 polymorph, which exhibits limited dissolution. These properties are discussed with respect to structure and thermodynamic stability.
