The influence of Fe³⁺ doping on thermally induced crystallization and phase evolution of amorphous calcium phosphate

Abstract

The present study investigates thermally induced crystallization and phase evolution of amorphous calcium phosphate (ACP) partially substituted with Fe3+ ions (M/P = 1.5 : 1). It was demonstrated that the...

Peculiarities of the formation, structural and morphological properties of zinc whitlockite (Ca18Zn2(HPO4)2(PO4)12) synthesized via a phase transformation process under hydrothermal conditions

“…At the same time, a very broad peak centered at around 30° was also observed, which is characteristic of amorphous calcium phosphate. 35 The FTIR spectrum of the as-precipitated powders (Fig. S4†) was completely different compared to that of DCPD 36 and contained only a few broad bands.…”

Effect of inositol on the thermally induced crystallization and phase evolution of amorphous calcium phosphate

“…22 Trivalent cations such as Fe 3+ completely prevent the formation of α-TCP and form CDHA. 23 However, there have been a few studies on the effect of small organic molecules on the thermal crystallization and phase evolution of ACPs. Normally such molecules would influence the storage stability of ACPs via electrostatic interaction between the positively charged Ca 2+ and negatively charged groups.…”
