“…Some researchers believed that C12A7 may easily form a glass which leads to its absence in C–A phase diagrams . Based on experience of phase diagram study, some attempts were made to recalculate/optimize C–A system from thermodynamic data of Brain 1989 (as listed in Table ).…”

Crystal structures, characteristics, and preparations of 12CaO·7Al2O3 family and CaO–Al2O3 (C–A) system have been reviewed in detail with relevant thermodynamic parameters being assessed or recalculated. 12CaO·7Al2O3 (shortened as C12A7) can form several derivatives of type C12A7:Mn− or C12A7–Mn− through replacing so‐called “free oxygen ion” by many anions including OH−, H−, O−, O2−, F−, Cl−, and e− in their cages, or being adopted by rare earth metals or alkaline earth metal oxides at cation sites (Ca2+ or Al3+). These doped C12A7 derivatives show unique material properties of transparent conduction, catalysis, and antibacterial with potential applications in fast ion conductors, optoelectronics, oxidants, and catalysts etc.

A partial isothermal section at 500°C was determined for this ternary system by [1982Tyv], which depicted a ternary compound Al 30 Dy 7 Zr 3 . Recently, [2011Yua] determined a full isothermal section at 500°C, confirming the existence of this ternary compound. Binary SystemsThe Al-Dy phase diagram [Massalski2] depicts the following intermediate compounds: aAl 3 Dy (D0 24 , Ni 3 Titype hexagonal), bAl 3 Dy (Al 3 Ho-type rhombohedral), Al 2 Dy (C15, MgCu 2 -type cubic), AlDy (AlEr-type orthorhombic), Al 2 Dy 3 (Al 2 Zr 3 -type tetragonal), and AlDy 2 (C23, Co 2 Si-type orthorhombic). The Al-Zr phase diagram [Massalski2] depicts the following intermediate phases:Al 3 Zr (D0 23 -type tetragonal), Al 2 Zr (C14, MgZn 2 -type hexagonal), Al 3 Zr 2 (Al 3 Zr 2 -type orthorhombic), AlZr (B f , CrB-type orthorhombic), Al 4 Zr 5 (Ga 4 Ti 5 -type hexagonal), Al 3 Zr 4 (Al 3 Ir 4 -type hexagonal), Al 2 Zr 3 (Al 2 Zr 3 -type tetragonal), Al 3 Zr 5 (D8 m , W 5 Si 3 -type tetragonal), AlZr 2 (B8 2 , Ni 2 Intype hexagonal), and AlZr 3 (L1 2 , AuCu 3 -type cubic). There are no intermediate phases in the Dy-Zr system [Massalski2]. Ternary Isothermal SectionWith starting metals of 99.99% purity, [2011Yua] arcmelted under Ar atm a number of binary and ternary alloys. The alloys were given a final anneal at 500°C for 720 h and quenched in water. The phase equilibria were studied with x-ray powder diffraction and scanning electron microscopy with energy dispersive x-ray analysis. The isothermal section constructed by [2011Yua] at 500°C is shown in Fig. 1. The ternary compound Al 30 Dy 7 Zr 3 (labeled s; AuCu 3 -type cubic) is present. The binary compounds AlDy 2 , Al 2 Dy 3 , AlDy, Al 2 Dy and Al 3 Dy dissolve 11.5, 7.8, 2.4, 22.5 and 2.5 at.% Zr respectively. The phases Al 3 Zr 5 and Al 4 Zr 5 are not stable at this temperature.
