{\mathsf {8\ Mg+Ca_{3}(PO_{4})_{2}\ {\xrightarrow {\tau ^{o}C}}\ Mg_{3}P_{2}+3\ CaO+5\ MgO}}

{\ displaystyle {\ mathsf {8 \ Mg + Ca_ {3} (PO_ {4}) _ {2} \ {\ xrightarrow {\ tau ^ {o} C}} \ Mg_ {3} P_ {2} +3 \ CaO + 5 \ MgO}}}

Magnesium phosphide forms bright yellow cubic crystals, cubic syngonies , space group I a3 , cell parameters a = 1.201 nm, Z = 16.

Thermally stable, melts at high temperature.
