HYDRATION-HARDENING PROPERTIES OF DIVALENT CATION-SUBSTITUTED α-TRICALCIUM PHOSPHATE

HYDRATION-HARDENING PROPERTIES OF DIVALENT CATION-SUBSTITUTED α-TRICALCIUM PHOSPHATE

Divalent cation-substituted α-phase tricalcium phosphates (α-Ca3-xMx(PO4)2, where M = Mg, Zn, Sr, Ba) were obtained by heating at 1500 °C for M=Mg (x = 0.03), 1400 °C for the others (x = 0.09), respectively. The resulting products were characterized by XRD, hydration reactivity and hydration-hardeni...

Zusammenfassung:Divalent cation-substituted α-phase tricalcium phosphates (α-Ca3-xMx(PO4)2, where M = Mg, Zn, Sr, Ba) were obtained by heating at 1500 °C for M=Mg (x = 0.03), 1400 °C for the others (x = 0.09), respectively. The resulting products were characterized by XRD, hydration reactivity and hydration-hardening strength. The hydration reactivity of these α-phase phosphates was decreased by the substitutions, regardless of smaller or larger M in ion size than Ca, i.e., the α phase was chemically stabilized.
