“…In fact, samples from A to F show similar values of setting times, likely due to a similar amount of formed struvite. The combined characterization of the set cements by means of XRD, FE-SEM, and thermal analysis allowed us to gain insights into the type of phases present in the cement: it is known from the literature that TMP and DAHP react forming struvite as a binding phase, 42 whereas the nature of citrate inclusion in the cement matrix is not known. In particular, the goal of this investigation was to understand if this ion is included in the inorganic matrix as an unreacted material or if it can react with TMP, thus forming a new binding phase.…”

“…Cements. The initial consistency and the handling properties of the pastes were evaluated by observing their appearance immediately after mixing (see Figure 1): when TMP powder (characterization reported elsewhere 42 ) is mixed with DAHP and DAC-based solutions, an easily moldable paste quickly forms. As the citrate content in the formulation increases, pastes appear more uniform and less viscous, displaying improved handling properties.…”

“…187 Magnesium phosphate-based cements (MPCs) might replace the wide application of calcium phosphate-based cements (CPCs), due to the synthetical excellent mechanical properties, degradation rate and pronounced bone regeneration capacity. 187,188 Gelli et al 189 proved that the use of 2.0 M and 3.5 M DAHP solution contributes to the formation of compact and hard cements, the compressive strength grows with the powder to liquid ratio and the concentration of DAHP solution increases, while inversely proportional to the total porosity of MPCs. Kanter et al 190 demonstrated that the struvite cements (MgNH 4 PO 4 Á6H 2 O) dissolved completely after 10 months and the degradation rate of cement matches with the new bone formation rate at both unloaded and mechanically load-bearing defect sites.…”

“…The compact and hard cements were formed with di-ammonium hydrogen phosphate concentration of 2.0 M and 3.5 M. And the compressive strength of MgP cements increased with the P/L ratio and with the concentration of di-ammonium hydrogen phosphate solution, while the total porosity of MgP cements showed an opposite trend. 105…”
