“…Nevertheless, whereas ternary sections involving these oxides with rare-earth oxides have been systematically determined (refe rence [2] and references therein), combinations of CuO and (BaO, SrO or CaO) with a transition metal oxide are still poorly investi-gated. In the case of SrO, the exceptions encompass systems in which the transition element is V [3], Nb [4,5], Fe [6], Ti [7,8], Zr [8], Hf [8], Ta [9], W [10] and Co [11]. The CuO -SrO -ZnO system does not appear to have been stu died.…”

The subsolidus phase equilibria of the CuO-SrO-ZnO system were determined at 900 °C in air. The pseudoternary section does not contain ternary oxide phases but is made of 5 three-phase regions and 2 narrow two-phase regions linked to a Sr 14 Cu 24-x Zn x O 41-y solid solution. The maximum solubility of Zn in this phase is limited to x ≈ 0.1, but this low doping level results in a significant decrease of the electrical resistivity by about one order of magnitude compared to the undoped compound. The other binary oxide phases SrZnO 2 , Sr 2 CuO 3 , and SrCuO 2 do not form solid solutions extending into the ternary system. SrZnO 2 was found to decompose upon contact with ambient air.

“…In air at 900 • C, only one ternary oxide compound was found for the IVB group elements [18]. Studies devoted to systems involving elements from the VB group revealed the existence of several ternary oxides (SrV 2 CuO 7 , Sr 3 Nb 2 CuO 9 and Sr 3 Ta 2 CuO 9 ) as well as several ternary solid solutions [19][20][21][22]. Finally, in the SrO-Fe 2 O 3 -CuO system, a new ternary oxide compound with Sr 7 Fe 17 CuO 34 composition was evidenced by Yang et al [23].…”
