Bi-2222 phases were prepared by solid state reactions and were studied using X-ray diffraction, chemical and EDS-analysis. Compounds with composition Bi2Sr2R1.33Ce0.67Cu2O10+δ were obtained for R=Pr, Nd, Sm-Er. The phases Bi2Sr2Cu2O10+δ with similar structure but without Ce were prepared for R = Pr, Sm-Dy. For Bi2Sr2Eu2-xCexCu2O10+δ the solubility limit was determined and the effect of treatment under different oxygen pressures was investigated. Weak diamagnetic signals (<3%) were detected for some of these samples.
