• Liquidus isotherms and phase equilibria have been determined experimentally for a pseudo-ternary section of the form “MnO”–(CaO+MgO)–(SiO2+Al2O3) with a fixed Al2O3/SiO2 weight ratio of 0.17 and MgO/CaO weight ratio of 0.25 for temperatures in the range 1 393–1 673 K.The primary phase fields found in the investigated section include manganosite (Mn, Mg, Ca)O; dicalcium silicate α-2(Ca, Mg, Mn)O·SiO2; merwinite 3CaO·(Mg, Mn)O·2SiO2; melilite [2CaO·(MgO, MnO, Al2O3)·2(SiO2, Al2O3)]; wollastonite [(Ca, Mg, Mn)O·SiO2]; diopside [(CaO, MgO, MnO, Al2O3)·SiO2]; tridymite (SiO2); rhodonite [(Mn, Mg, Ca)O·SiO2]; anorthite (CaO·Al2O3·2SiO2) and tephroite [2(Mn, Mg, Ca)O·SiO2].The liquidus temperatures and primary phase fields are significantly different to those in the ternary system “MnO”–CaO–SiO2, but are close to those previously reported pseudo-ternary section “MnO”–(CaO+MgO)–(SiO2+Al2O3) for Al2O3/SiO2 weight ratio of 0.17 and MgO/CaO weight ratio of 0.17.The partitioning of CaO, MgO and MnO between liquid and solid phases was measured using EPMA, and the extents of solid solutions for a range of bulk compositions and temperatures were characterised.
