The known data for the phases Sr6Bi2O9, Sr3Bi2O6, Sr2Bi2O5, Sr18Bi22O51, Sr6Bi14O27, SrBi4O7, Sr2Bi6O11, SrBi2O4, Sr8Bi10O23, Sr8Bi2O11, Sr5Bi6O14, Sr6Bi2O11, Sr6Bi4O15 and Sr24Bi14O52 have been revised and corrected, unknown data have been estimated. The values of Delta H-298(0), S-298(0), H-297(0)-H-0(0), the T and Delta H values for the phase transformations, C-p(T) for the crystalline state, C-p at T > T-ph.tr, and also the polynomial approximating a reduced Gibbs are presented.
