N2 - The stability of Hg1-xBa2Can-1CunO 2n+2+δ [Hg12(n - 1)n] and its competing phase, HgCaO2, at synthesis temperatures were studied in terms of their equilibrium Hg vapor pressure PHg. It was found that the stability of Hg12(n - 1)n varies with n in a complex way. It was also observed that traces of moisture and/or carbon dioxide reduce the PHg of HgCaO2, while partially substituting Re, Pb and Mo for Hg suppresses the PHg of Hg12(n - 1)n. Possible relationships between the beneficial substitution effect, the change of cation valence, and the defect structures in Hg12(n - 1)n are proposed.
