Possible Interaction: Calcium Phosphate and Iron, Dietary

“Addition of 0.25 wt.% Fe (0.25 Fe-TCP) increased the compressive strength of β-TCP from 167.27 ± 16.2 to 227.10 ± 19.3 MPa.”

“Our results showed that Fe addition at concentrations of 0.5 wt.% (0.5 Fe-TCP) and 1.0 wt.% (1.0 Fe-TCP) inhibits the β-TCP to α-TCP phase transformation at sintering temperature of 1250 °C.”

“Regression analysis of the data revealed that both ascorbate and citrate emerged as equally strong enhancers while tannate and calcium phosphate demonstrated strong inhibitory effect on iron availability in the STD meal.”

“The incorporation of iron ions in the β-TCP lattice decreased the specific surface area as the pore size was shifted toward meso- and/or macropores.”

“Thus, iron appears to be a useful tool to enhance the osteoconductive properties of calcium phosphate ceramics.”

“We propose that the diminished solubilities of zinc, iron , copper, magnesium, and citrate are linked to the precipitation of calcium phosphate through one or more mechanisms of coprecipitation.”

“… Fe … β-tricalcium phosphate (β-TCP)/ dicalcium phosphate dihydrate (DCPD) ratio and prolongs the initial and final setting time due to effective role of Fe on stabilizing … its dissolution kinetic, in a dose dependent manner where the highest setting time was recorded for 1.00 wt.% Fe-BrC sample.”

“In addition to chemical precipitation, however, it is also possible for the iron to be removed by adsorption on an amorphous precipitate such as calcium phosphate.”
