Equilibrium diagrams for the joins CaAl 4 O 7 ‐MgAl 2 O 4 , CaAl 4 O 4 ‐Ca 2 Al 2 SiO 7 ‐MgAl 2 O 4 , and Ca 2 Al 2 O 4 –Ca 2 Al 2 SiO 7 ‐MgAl 2 O 4 were determined by the classical quenching method and hot stage microscopy. Liquidus relations in the quaternary subsystem are discussed. Two univariant curves are located within the composition tetrahedron. The quaternary invariant point is a peri‐tectic. Technological application of results is indicated.
