Thermodynamic modeling of magnesium ammonium phosphate

Magnesium ammonium phosphate cement (MAPC), which is one type of MPC, was first patented by Prosen in 1936 as a binder material to produce dental casting investment materials by mixing MgO with ammonium phosphate. MAPC can release noxious gaseous ammonia during the hardening process, which impedes its application in construction.
