Stability of tricalcium phosphate polymorphs in the Ca3(PO4)2–Zn3(PO4)2–Mg3(PO4)2 system and solid-state compatibilities of CaO–P2O5–MgO–ZnO system at 900 °C

Stability and microstructure of tricalcium phosphate polymorphs (TCP) in the Ca 3 (PO 4 ) 2 –Zn 3 (PO 4 ) 2 · Mg 3 (PO 4 ) 2 phase equilibria diagram from experimental studies between 1200 ◦ C and 1400 ◦ C have been determined. Solid-state compatibilities in the CaO–P 2 O 5 –MgO–ZnO system were defined at 900 ◦ C for P 2 O 5 ≤
