This paper reports on a Mg-substituted material with nominal composition Bi{sub 2}Sr{sub 2}Ca{sub 3}Mg{sub 2}Cu{sub 6}O{sub x}, prepared by partial substitution of Ca by isovalent Mg in the 2256 composition of Bi-Sr-Ca-Cu-O, studied by the measurements of electrical resistance, magnetic susceptibility and x-ray diffraction pattern. Results show the existence of a superconducting phase with onset T{sub c} at 112l.5 {plus minus} 1 K along with a minor phase with onset T{sub c} = 88 K. The material retained superconducting characteristics (Meissner effect and T{sub c}{sup onset}) even after a period of six months.
